Lorlin Electronics, the UK’s longest established switch manufacturer, has released the MDSP pushbutton dimmer switch. The UK manufactured MDSP is a push-on, push-off switch with a potentiometer mounted on the same spindle. Widely used in domestic lighting dimmer controls the MDSP is now finding acceptance in many other industrial and professional switching and control applications.

The MDSP offers a wide range of potentiometer resistance values, including nonlinear and is available with either printed circuit terminals, inline or staggered terminals.

Switch operation force is nominally 15N, with optional tactile feel and other switch forces being available.

All moulded components are in UL94V0 rated materials.

A 4.0 or 6.0mm diameter polyamide or 4.0mm metal spindle may be specified at whatever length customers require.

Secure panel mounting is provided by an M10 x 1.0mm bush thread.

The switch offers a single-pole changeover, rated at 10A (2.5A at 250V AC resistive) and life expectancy is greater than 25,000 cycles.

Operating temperature range is -25 to +100C and the unit has a withstand voltage of 2500V AC.

The potentiometer has a track life of over 50,000 cycles, operates over a 270-degree range and may be specified to give 0ohm to maximum resistance, or maximum resistance to 0ohm over its clockwise rotation.

The MDSP is fully approved to international safety standards including EN61058 by VDE, Semko, Nemko, Demko and Femko.

Dan Walker, Sales Manager for Lorlin comments: ‘Our new MDSP has been very well received by lighting equipment manufacturers and we are now able to look for out of the box applications by developing new markets in fan and motor control and industrial processes’.

The Lorlin MDSP is available direct from the factory as well as a wide number of international franchised distributors.

The MDSP push-push-pot is suitable for use in domestic light dimmers and fan speed controllers, industrial automation and process control as well as office and stage lighting, test equipment and instrumentation.
