COMMERCIAL GRADE PUSHBUTTONS

MOMENTARY ACTION, SEALED, SNAP-ACTION, DOUBLE BREAK

P3

COMMERCIAL

PUSHBUTTONS

Makes and breaks every time! Less than 25mΩ contact

resistance because the OTTO design features inherent rocking

action that breaks welds and wipes contacts clean.

The P3 is the commercial version of the P1 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 protects the contacts and terminals from hostile

environments and solder flux.

High contact force (120g/4.2 oz), low contact resistance

(25mΩ max) 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 low 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 your

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.
