C&K - IP68-Sealed, Rugged Pushbutton Switch for Harsh Environments

C&K Components, a leading international supplier of pushbutton switches, tact switches, toggle and rocker
“These pushbutton switches feature a robust design including gold-over-silver contacts for low-power applications or silver-plated contacts. The IP68 sealing and extended life cycles make them ideally suited for high reliability applications where repair is near impossibly,” said, Gary Mountford, General Manager, C&K Components. “Coupled with multiple housing styles and wire lead options, the switches offer an ideal solution for designers who are seeking a rugged component.”

The NP series features an aluminum housing that is RoHS-compliant. Actuation force is 8N ± 1N, and travel to contact is 1.6 ± 0.15mm with an over travel rated at a minimum of .045. Total travel to contact is 1.6 ± 0.15mm. The rugged switch is able to withstand a vibration force of 10-500Hz per 10g and a shock rating of 50g 11ms sawtooth wave.

The pushbutton switch offers a maximum switching ability rated at 2A of current, contact resistance of 50mΩ and dielectric strength of 1000V AC for 1 min. Voltages are 10mA/5 VDC for the gold-over-silver contact material specified for low-power applications. The silver contact option provides voltage ratings of 1A/28 VDC at 1,000,000 cycles, 5A/28 VDC at 25,000 cycles (resistive) and 3A/28 VDC at 25,000 cycles (inductive).

Operating temperatures for the NP series ranges from -55°C to +105°C.
