Lorlin Electronics has announced the its new MDSP push button switch. The UK manufactured MDSP is a push-on, push-off switch with a potentiometer mounted on the same spindle and will find wide acceptance in many industrial and professional switching and control applications.

The MDSP offers a wide range of potentiometer resistance values, including non-linear and is available with either printed circuit terminals, in line or staggered terminals. Switch operation force is nominally 15N, with optional tactile feel and other switch forces being available. All moulded components are in UL 94V-0 rated materials. A 4.0mm 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 change over, rated at 10A (2.5A @250VAC resistive) and life expectancy is greater than 25,000 cycles. Operating temperature range is –25 to +100°C and the unit has a withstand voltage of 2,500VAC.

The potentiometer has a track life of over 50,000 cycles, operates over a 270° range and may be specified to give 0Ω to maximum resistance, or maximum resistance to 0Ω over its clockwise rotation. The MDSP is fully approved to international safety standards including EN61058 by VDE, SEMKO, NEMKO, DEMKO and FEMKO.

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