MOMENTARY ACTION, SEALED, SNAP-ACTION, DOUBLE BREAK
The P1 offers a mechanical life that is well beyond the 50,000
cycles required by MIL-PRF-8805. The dual break switching
mechanism has an incredibly fast transfer time, reducing arcing
and increasing contact life. The inherent wiping action breaks
welds and scrubs the contacts clean on every actuation.
The P1 switch offers vastly improved life under extreme conditions
found in most military environments. Moistureproofing is
accomplished in two ways. The pushbutton is sealed with 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 to Commercial (IP68S) and Military (MIL-PRF-
8805 Design 3) standards are available. This watertight design is
also available in commercial construction as the P3 series (add
“W” to your part number).
High contact pressure (120g/4.2 oz), low contact resistance
(25m max) and short contact bounce (5ms max) result from
our patented snap-action mechanism. These characteristics
guarantee exceptional current carrying capabilities over the
life of the switch. With the optional low level (gold plate)
configuration, the P1 is well suited to interface directly to
computers and other solid state devices.
The P1 switch is a quality precision snap-action switch designed
for use in panel boards, control grips, computers, instruments,
pressure switches and other hand or machine operated
applications where sealed pushbutton switches are required. Its
precision permits the P1 to be used as a limit switch with unique
size, high electrical ratings and a wide choice of mounting styles.
