Following its recent exclusive licensee agreement with Duraswitch Industries, GGI International has released three new switch technologies: PushGate, Thincoder RT, and MagnaMouse. The PushGate is a revolutionary new pushbutton switch that presents all the possibilities of a standard pushbutton switch and more. Its crisp, consistent tactile feedback, coupled with its durability, reliability and its ability to be environmentally sealed, makes this technology an attractive option for most control panels.

Due to the simplicity of the armature and magnetic components used to activate the switching circuitry, PushGate integrates easily with flexible circuits or PCBs and is compatible with other switch products, including Thincoder RT and MagnaMouse.

With full key illumination capabilities, PushGate allows for easy backlight integration while maintaining its tactile feel.

Lastly, custom designs are available for multiple outputs and shielding requirements.

The name thiNcoder RT says it all.

This next generation technology is a thin, encoder rotary switch.The Thincoder RT is the only encoder in the world, which can be mounted to a flexible circuit.

The key to this technology is its possibilities for integration.

Having both pushbuttons and rotors on the same flexible circuit and panel, offers a wide range of possibilities, increased flexibility as well as significant cost advantages.

In addition, its design is truly innovative.

Its gold plated balls in conjunction with magnets and a flexible circuit, opens and closes the circuit as the knob is turned.

This friction free process provides greater durability compared to other similar technologies.

The MagnaMouse multidirectional switch provides unlimited motion capabilities.

This next-generation technology can replace current products such as computer cursors, game controls, joystick controls, temperature settings and many other electronic devices that use a multi directional switch.

The simple design of MagnaMouse, an armature with a centre pivot point, offers durability and cost advantages.

Furthermore, its simple flat panel integration allows for digital or analogue designs.

A new patented optical trackerball device that will operate fully immersed in liquid is now available from Micromark C and CD. The device from Cursor Controls has been developed in response to specific demands from the industrial, military and marine markets and will not only work underwater but also with coffee, cola and even beer. This patented design has full IP68 seal rating against liquid ingress, enabling it to endure the toughest of operating environments.

The cursor controller for screen-based systems is available in 38 and 50mm ball sizes with a choice of quadrature, PS/2 or USB outputs.

Visitors to the Hanover Messe in April were shown a demonstration of an optical 38mm version trackerball device working underwater for five days continuously.

Each unit is designed to give minimum contact with the ball and achieve the best feel of any trackerball currently available.

GGI International has released Canada’s first vandal-resistant keypad. As the exclusive Canadian licensee of Duraswitch technologies, GGI reckons it can now offer the perfect solution for keypads that are often subject to abuse and vandalism. This new switch construction, named the “High-Impact PushGate”, incorporates a layer of rubber covering the top of the basic PushGate construction to prevent damage to the switch.

This new High-Impact PushGate, is composed of the standard switch construction, a rubber layer and a graphic overlay.

This design maintains a unique, crisp, consistent, tactile feel, which is easily environmentally sealed.

This new construction was developed because the market place required a switch that could withstand everyday abuses, for example the actuation of a control panel by a gas nozzle, car keys or simply rough, repeat use.

“Manufacturers will be attracted to the new High-Impact PushGate because it means less down time which translates into higher levels of efficiency, reliability and profitability”, said Ian Graham, Co-President of GGI International.

“The market is looking for innovation, quality and products that push the limits, and that is what we are providing”.

The High-Impact PushGate is a perfect solution for gas pump controls, ATMs, security entrance keypads, industrial controls, kiosks, car washes, POS, exercise equipment, farm implements etc.

“GGI strives to fulfil the market’s need for customised front panel interface solutions, and the High-Impact PushGate is yet another example of GGI’s commitment to supply innovative solutions to its clients”, said Peter Graham, Co-President GGI International.

Door opener switches on public transport and switches mounted on traffic lights are both subjected to extreme demands. Rough environmental conditions and vandalism cause specific problems for switches in these applications. The PSE HI range of high impact piezo switches from Schurter are designed specifically for these applications.

Piezo switches do not feature any of the moving parts found in mechanical switches, and so even under continuous operation there is no risk of loss of functionality due to wear.

In laboratory tests, a life expectancy of over 20 million actuations has been achieved, which makes the new switches virtually service free.

The PSE HI features enhanced vandal-proof protection.

The innovative and patented construction of the switch offers a higher impact resistance of IK06 to DIN EN50102 specifications.

These completely sealed switches feature fully encapsulated electronics within the housing.This ensures that neither fluids nor dust can penetrate inside the switch.

The switch meets IP67 specifications.

The PSE HI switches are part of the Schurter Metal Line product family, and are available with mounting diameters of 22 and 27mm.

Both the actuating surface and the body of the switches are made from high-grade stainless steel.

The use of this robust material makes these switches particularly well suited for outdoor applications and rough environments.

Various standard typefaces are available for in-house laser engraving of the actuating surface.

Customer specific fonts and symbols can also be specified.

PushFlex is an all-new switch technology that combines a readily available magnet sheet and a magnetically receptive actuating layer to create a unique switch construction.
PushFlex is an all-new switch technology that combines a readily available magnet sheet and a magnetically receptive actuating layer to create a unique switch construction. Bob Brilon, Duraswitch President and CEO, said: “This innovation and elegant solution incorporates key benefits for the high volume market segments including low cost, high reliability and tactile feedback, while at the same time using standard materials and common manufacturing equipment”. “For certain applications, cost is the driving, if not sole, factor in determining which type of tactile switch element will be used.

PushFlex offers a cost competitive, highly customisable pushbutton alternative”, added Tim Kuhn, Vice President Business Development.

PushFlex technology combines a commonly available magnet sheet and a magnetically receptive actuating layer to create a unique switch construction.

The actuating layer is a slotted flat configuration which aligns to holes cut in the magnetic layer.

Together these layers form a web of switches.

“Because keys are cut into the layers, a manufacturer can have a few to dozens of switches on a panel with relatively little increase in overall cost”, continued Kuhn
PushFlex is simple to manufacture, and offers an alternative to both domes and conductive rubber keypads.

The web configuration of PushFlex eliminates the need for individual placement of domes, keeping assembly costs down.

The entire sourcing and moulding process for conductive rubber keypads is eliminated.

With PushFlex, significant cost advantages can be achieved in both low- and high-volume production.

PushFlex offers several design options including constructions for use under plastic keycaps or standard graphic overlays.

Feel and travel can be customised to meet varying specifications, and normally closed key options can easily be incorporated.

Kuhn said: “Because it offers a compelling cost-per-key value proposition, our design specifications for PushFlex were aimed at developing the technology for applications with numerous pushbuttons like a typical keyboard configuration”.

As part of the rollout for PushFlex technology, leading industry publications such as EDN Magazine and SMT Magazine are evaluating the technology for their annual innovation awards.
“Magnetic properties are uniquely employed in all of Duraswitch’s licensed technologies, so Duraswitch has already established relationships with major magnet suppliers such as Arnold, Magnum Magnetics and Max Baermann.

These relationships will help us in the final materials selection for PushFlex”, added Van Zeeland.

“PushFlex brings together a host of benefits in a very efficient package and we believe this development will not only attract interest of the industry, but also its suppliers”.

Surface mount conductive polymer capacitors combine ultralow equivalent series resistance with the lowest inductance available on the market for products of this type.

Kemet has launched a new series of face down termination conductive polymer capacitors. The new surface mount devices combine ultralow equivalent series resistance (ESR) with the lowest inductance (ESL) available on the market for products of this type. Initial offerings of the T528 series, which specifies an inductance of less than 0.7nH at 20MHz, are targeted at high-speed server and microprocessor decoupling applications that are driving demand for low inductance parts.

Featuring terminations on the underside of the component as opposed to standard wrap-around terminations, the T528 series is initially being offered with a 330uF capacitance and rated voltage of 2.5V.

A choice of 9 or 12mohm ESR parts is available.

Both are housed in low profile Z-size cases measuring 7.3 x 4.3mm and with a height of just 1.7mm.

The new polymer capacitors feature a nonignition failure mode and a self-healing mechanism.

They are RoHS compliant and suitable for use over a temperature range of -55 to +105C.

Parts are available in tape and reel packaging ready for use in automated assembly processes.

New from Link Microtek is a family of surface-mount clock oscillators and VCXOs that not only offer high performance but are available with exceptionally short lead times.

New from microwave and RF component specialist Link Microtek is a family of surface-mount clock oscillators and VCXOs that not only offer high performance but are available with exceptionally short lead times of typically 2 weeks or less. Manufactured by MtronPTI, the M210x series clock oscillators and M310x series VCXOs utilise the company’s ‘QiK Chip’ ASIC-based technology to deliver a wide frequency range of 150MHz to 1.4GHz and a low integrated jitter value of typically 0.3ps, which is comparable with more expensive SAW-technology alternatives. In terms of thermal stability, the new devices outperform SAW equivalents: using a standard AT-cut crystal resonator, the QiK Chip products achieve stabilities of +/-20ppm over the industrial temperature range of -40 to +85degC, compared with typical values of +/-100ppm over the more limited range of -20 to +70degC for SAW-based oscillator designs.

Fully RoHS compliant, the M210x clock oscillators and M310x VCXOs are available in either 7 x 5mm leadless or 14 x 9mm J-lead ceramic packages andcan be specified with supply voltages of 1.8V, 2.5V or 3.3V and a choice of LVPECL, LVDS or CML compatible outputs.

The combination of high performance and short lead times is expected to make the new devices particularly attractive for applications such as high-speed Ethernet, microwave radios, advanced Sonet systems, and high-precision test and measurement equipment.
