P3
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.
