C and K’s new range of rugged pushbutton switches target harsh environments, off-road, industrial, transportation and military applications requiring strong switch feedback and high-current switching.

Designated the NP series, the switches feature 1,000,000 life cycles and are sealed to IP68 specifications.

Capable of up to 5A resistive load, the NP series switches have wire or solder termination options and can be mounted by a threaded front or rear mount and slot mount.

‘These pushbutton switches feature a robust design, including gold-over-silver contacts for low-power applications or silver-plated contacts,’ said Gary Mountford, general manager, C and K Components.

‘The IP68 sealing and extended life cycles make them ideally suited for high-reliability applications where repair is near impossible,’ he added.

‘Coupled with multiple housing styles and wire lead options, the switches offer an ideal solution for designers who are seeking a rugged component,’ said Mountford.

The NP series features an aluminum housing that is RoHS-compliant.

Actuation force is 8 +/-1N and travel to contact is 1.6 +/- 0.15mm with an over-travel rated at a minimum of 0.045.

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 50m and dielectric strength of 1,000V AC for 1min.

Voltages are 10mA/5V DC for the gold-over-silver contact material specified for low-power applications.

The silver contact option provides voltage ratings of 1A/28V DC at one million cycles, 5A/28V DC at 25,000 cycles (resistive) and 3A/28V DC at 25,000 cycles (inductive).

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

C and K Components will be exhibiting at Electronica on 9-12 November 2010 in Munich, Germany.
