Door interlock pushbutton switches with latching or momentary actions offer design flexibility

A new series of C&K interlock door switches is now available from TTI. The DS Series door interlock switch offers flexibility as it has latching or momentary actions and can be used as an interlock switch, detection switch or circuit interrupt switch. Typical applications include gaming and vending machines. The DS Series switches have a push/pull feature to break power when the machine door is opened for trouble-shooting, maintenance and repair. The DS Series is flexible, enabling many design options thanks to their unique construction, which combines quick assembly with a long operating life of 50,000 cycles at 10A. The interlock switches are available as single-pole, double-throw or double-pole double-throw with snap-in style mounting. The reliable snap action actuator is available in three actuator styles: momentary, short button, momentary, long button and monetary/pulled out button. There is a choice of three different terminals which can be specified on ordering and three electrical ratings: D6, D7 and F5. The F5 rated switches can also be specified for extended electrical life of 100,000 cycles on request. Further electrical specifications include dielectric strength of 1500V (50-60Hz at sea level), and insulation resistance of 100Mohm minimum and initial contact resistance of 30mohm. Suitable for operating environments between -40C to- +85C, the DS Series interlock pushbutton switches feature rugged copper alloy, silver-plated common terminals and F5-rated, gold-plated over silver alloy contacts for robust performance. They are RoHS-compliant and halogen-free, says the company.
