The OTTO P1 series pushbutton switch offers vastly improved life under extreme conditions found in most military environments. Moistureproofing is accomplished in two ways. The pushbutton is sealed with a silicone boot operating on our patented “rolling sleeve”, providing longer life and smoother operation over a wide temperature range. Epoxy seals protect the contacts and terminals from hostile environments and solder flux.

Watertight sealing (submergible) to 1 meter (IP68) water pressure is available but not as a military approved version as there are no Military specifications. This watertight design is also available in commercial construction as the P3 series. Add “W” to your part number.

Higher than normal (120 grams) contact pressure, amazingly low (25 milliohms max. standard) contact resistance and extremely low contact bounce are all the result of the OTTO patented snap-action mechanism. Extra long electrical life and precise trip point offer added value and precision operation.

APPLICATIONS: The OTTO P1 series is a quality precision snap-action switch designed for use in panel boards, control sticks, computers, instruments, pressure switches and other hand or machine operated applications where sealed pushbutton switches are required. Its precision permits the OTTO P1 to be used as a limit switch with unique size, high electrical ratings and a wide choice of mounting styles.
