Specifications Subject To Change Without Notice
MOMENTARY ACTION, SEALED, SNAP-ACTION, DOUBLE BREAK
Makes and breaks every time! Less than 25m 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 pressure (120g/4.2 oz), low contact resistance
(25m max) and short contact bounce (5ms max) are the result
of our patented 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.
