P7-D
SEALED PUSHBUTTON SWITCHES
DOME
PUSHBUTTONS
MOMENTARY ACTION, ATTRACTIVE & RUGGED FOR WET & DUSTY ENVIRONMENTS
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 moisture-
proof sealed construction excellent mechanical and electrical
performance while operating under the most severe conditions.
1 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.
This quality precision snap-action switch is designed for use
in instrument panels, grips, computers, heavy equipment and
other applications where attractive rugged pushbutton switches
are required.
Features:
• Attractive dome style buttons
• Low level switching capability
• Less than 25mΩ contact resistance
• High contact pressure
• Six circuit variations
• Positive tactile feedback
• Variety of mounting styles
• Constructed in accordance with
MIL-PRF-8805/110 (no QPL)
• UL recognized
• Dusttight to IP64 & MIL-PRF-8805 Design 2 or
watertight to IP68S
