Recently C&K Components has developed a rugged snap-mount pushbutton switch for door interlock systems-- The DS Series interlock switch. The DS Series interlock switch provides latching or momentary actions to deliver a variety of integration options, including typical applications as a detection switch or a circuit interrupt in harsh environments. The single- or double-pole double-throw DS Series switches are RoHS-compliant and made of halogen free material.

C&K Components, a leading global manufacturer of tactile, toggle, rocker and pushbutton switches, and smart card interconnect devices.


The DS interlock pushbutton switch has rugged copper alloy, silver-plated common terminals and F5-rated, gold-plated over silver alloy contacts for robust performance. The dielectric strength of the DS switch is measured at 1500V (50-60Hz at sea level) and insulated at 100mΩ (minimum) with initial contact resistance rated at 30 milliohms.

“The DS Series switch allows for a multitude of new design options due to its unique construction that combines quick assembly and prolonged performance,” said Vinny Acampora, product manager at C&K Components. “The extensive electrical life of 100,000 cycles makes it ideal for multi-function security systems, gaming equipment, commercial appliances and even HVAC applications requiring frequent manual circuit interruptions.
