P7 - Subminiature, Sealed, Mil Grade MIL-PRF-8805/110

The rugged P7 pushbutton series incorporates OTTO’s patented double break design in a significantly smaller package than the P1 series. These subminiature switches embrace today’s technology requirements by allowing for a large number of switches to fit within a faceplate or a small panel space.

The long life snap-action design offers low contact resistance (25 milliohms max initial) and is protected from the environment by a silicone rubber boot, operating on a “rolling sleeve” principle that gives long sealed life and smooth operation. Mechanical life is 2 million operations. The P7 series is designed to meet the requirements of MIL-PRF-8805 including low level switching (10mA @ 30mV) with power switching up to 5 amps at 28VDC as well.

A variety of mounting styles are offered to best match the application. The P7-1, P7-2, P7-7 and P7-8 case styles feature a swaged bushing shape to allow press fit installation in aircraft flight control and hand grips and similar applications. The other styles feature threaded bushing mounting. The P7-3 and P7-A case styles have a front panel bezel, while the P7-5 and P7-6 have conventional bushings for rear panel mounted installations. Silver or black bezels are standard. Other colors available on special order.
