Makes and breaks every time! Less than 25 milliohms contact resistance because the OTTO design features inherent rocking-action that breaks welds and wipes contacts clean.

The OTTO P3 is the commercial construction version of the P1 series pushbutton switch, offering vastly improved life under extreme conditions found in some industrial environments. The pushbutton is sealed by 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, submersible to 1 meter (IP68) water pressure, is available. 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 P3 series is a quality precision snap-action switch designed for use in panel boards, computers, business machines, instruments, pressure switches and other hand or machine operated applications where sealed pushbutton switches are required. Its precision permits the OTTO P3 to be used as a limit switch with unique size, high electrical ratings and a wide choice of mounting styles.
