The P3 is the commercial version of the P1 pushbutton switch, offering vastly improved life under extreme conditions found in some industrial environments. Its inherent rocking action that breaks welds and wipes contacts clean. The pushbutton is sealed by a silicone boot operating on OTTO's patented “rolling sleeve,” providing longer life and smoother operation over a wide temperature range. Epoxy protects the contacts and terminals from hostile environments and solder flux.

High contact force, low contact resistance and short contact bounce are the result of our snap-action mechanism. These characteristics provide exceptional current carrying capabilities over the life of the switch. With the optional logic level (gold plate) configuration, the P3 is well suited to interface directly to computers and other solid-state devices.

Watertight sealing is available by simply adding “W” to the part number. Because the P3 is a double-break switch, wide connection possibilities, longer life and greater capacity are offered. The P3 design provides a unique terminal connection to the moving element for added flexibility. Special versions can be provided with five terminals to control up to four circuits.
