C&K's PNP3 series of sealed pushbutton switches with an additional no-cap option are intended for rugged applications such as control grip, off-road panels, industrial instruments, lifts, and conveyor controls.
Constructed in a black PBT/PC thermoplastic housing, the switches include an internal silicone rubber seal and are rated to IP68, making them ideal for harsh environments and for power wash-down applications, or anywhere the switch may be exposed to dust, water, or other damaging elements. PNP-series switches are tested for vibration (10 Hz to 500 Hz) and shock (up to 50 g) and are rated for up to 1,000,000 cycles.
The snap action provides positive tactile feedback while the lower operating force of just 3 N reduces operator fatigue. Designed for front panel mounting, the switches have a threaded body and are available with a dome bezel as a standard option. A range of actuator styles and colors are offered, and the PNP-series (including PNP8) switches may also be specified with the new no-cap option, allowing greater flexibility for designers.
Capable of handling resistive currents up to 5 A with silver contacts, a gold over silver contact option is available for low-current applications down to 10 mA. Circuit options include momentary action SPST NC, SPST NO, and SPDT – all with double break.
