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 offered in dusttight and
moistureproof sealed construction. Expect a minimum of 50,000
operations at full rated load of 5 amperes resistive or 3 amperes
inductive; up to a million operations in low signal switching
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.
Quality Features:
Attractive Dome style buttons
Low level switching capability
Low contact resistance .025 ohms max
High contact pressure
Six circuit variations
Positive tactile feedback
Variety of mounting styles
Sealed against dust and moisture
