Foremost Electronics has recently introduced its new Marquardt Mechatronik GmbH model 1683 pushbutton switch suitable for use in appliances requiring Class II protection.

Well suited for use in harsh industrial environments, including high dust and water areas, the 1683 pushbutton switch is protected to IP65 and IP67 levels and can control devices of up to 4,000W with its switching system for currents up to 16A. The double lifting contact system has a life endurance of over one million operations and has a number of different connection options including quick connect, solder and PCB terminals.

The switch can accommodate single- and double-pole contact options in the same package, with on/off and momentary actions. The switch cap is available in a range of colours and can be printed with customer legends and illuminated with either LED, glow lamp or a conventional filament bulb.

The 1683 pushbutton has electrical ratings for Europe of 16A (4) 250V AC – 10,000 cycles, 12A (8) 250V AC – 10,000 cycles, 10A (8) 250V AC – 50,000 cycles, and is approved to IEC/UL 61058 ENEC. It has an ambient operating temperature range of -20°C to 80°C and is flammability rated to UL 94 V-2.

Applications for the 1683 pushbutton switch include outdoor equipment, agricultural vehicles, construction vehicles, household appliances, medical equipment, laboratory equipment and industrial control.
