P7-D DOMED PUSHBUTTONS SEALED PUSHBUTTON SWITCHES ATTRACTIVE AND RUGGED FOR WET AND DUSTY ENVIRONMENTS These are P7-D series pushbutton switches with a contoured Dome style pushbutton. There are two design versions: flush dome and raised dome button profile. The switch series features short behind-panel depth. They also offer excellent mechanical and electrical performance while operating under severe conditions found in demanding applications. The OTTO P7-D Dome series is a double-break switch with a momentary circuit. Multiple contact variations are available. High contact pressure and unique contact design provide low contact resistance for low level switching capability as well as full rated service. Positive tactile feedback signals the operator when the switch is operated. Button legends are available on special order. The OTTO P7-D Dome series is a quality precision snap-action switch designed for use in panels, control sticks, computers, instruments, heavy equipment and other demanding applications where attractive, rugged pushbutton switches are required. Other P7 series models offer a wide choice of mounting styles.
