MPS-203R

The MPS-203R is a double-pole double-throw (DPDT) Miniature Pushbutton Switch with a single extended nickel-plated copper alloy actuator and silver plated brass snap action contacts. The 1977739-4 non-illuminated pushbutton switch features on-on operating function, 1/4-40 threaded bushing, chromed brass guard, epoxy seal and epoxy resin case (UL94V-0). It support wire lugs termination and vertical panel screw-on attachment mounting. It is use with the C22 cap. The new ALCOSWITCH blue series pushbutton is based on an innovative snap-action mechanism that produces an extremely fast switching moment. This high level of dynamics is not only reduces arcing and bounce but it also results in a high number of duty cycles. This miniature pushbutton is easily integrated into compact control/front panels. Despite its small case dimensions, the actuator gives a clear reliable feedback that confirms proper operation.
