The P7-D pushbutton switch is a momentary switch with a contoured dome style pushbutton. Two design versions are offered; flush dome and raised dome button profile. The P7-D features a shorter behind panel depth, dusttight and moistureproof sealed construction excellent mechanical and electrical performance while operating under the most severe conditions. one million operations at 1 amp resistive, 50,000 at full rated load of 5 amps resistive or 3 amps inductive. The P7-D is a double break switch with momentary circuit, the positive tactile feedback signals the operator when the switch is operated. Multiple contact variations are available as well as a variety of special order button legends. High contact pressure and unique contact design provide low contact resistance for low level switching capability as well as full rated service.
