Commercial and Military Specification Switches


The P7 series of military and commercial switches incorporates OTTO controls 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 (25mΩ max initial) and is protected from the environment by a silicone rubber boot, operating on a “rolling sleeve” principle that gives a long sealed life and smooth operation. With a mechanical life of 2 million operations our P7 switches are designed to meet the requirements of MIL-PRF-8805 including low level switching (10mA @ 30mV) with power switching up to 5 amps at 28VDC.

A variety of mounting styles are offered to best match the application. These include a swaged bushing shape for press fit installation in aircraft flight control and hand grips and similar applications. Other styles feature threaded bushing mounting, with a front panel bezel and conventional bushings for rear panel mounted installations. Silver or black bezels are standard. Other colours available on special order.

Pushbuttons are available in a choice of nine colours. A great deal of time was invested in ensuring an excellent tactile feedback assures the operator that contact transfer has been made. Particulary important for military switches.

Both Mil-Spec switches and commercial versions of these are offered: Moisture proof and dust tight to IP64 and MIL-PRF-8805 Design 2r watertight to IP68S and to MIL-PRF-8805 Design 3.
