The P8 Vandal Resistant series is a durable, robust switch,
offering the same quality and precision tactile feedback found in
the standard P8 series. With a variety of case, mounting and
terminal styles and a mechanical life of 1,000,000 cycles, this
stainless steel sealed switch is ideal for door access security
systems, public transit systems, emergency phones, traffic signals,
industrial and process control environments and anywhere that
ruggedness, durability and security are crucial.
OTTO P8 series pushbutton switches feature a shortened
back of panel depth while offering all the features of the regular
size P1 and P3 series switches. P8 series switches offer vastly
improved electrical and mechanical life under extreme conditions
found in most military and industrial environments.
On sealed models, a silicone boot operating on our patented
“rolling sleeve” principle protects the contact area against
contamination at the button area. This boot provides long life and
smooth operation over a wide temperature range. Sealed terminals
protect the contact area from hostile environments and solder flux
on both sealed and unsealed models.
High contact pressure (120g/4.2 oz), low contact resistance
(25mΩ) and short contact bounce (5ms max) are all a result
of our patented snap-action mechanism. These characteristics
provide exceptional current carrying capabilities over the life of
the switch. Optional low level (gold plate) configuration makes
the P8-V switches well suited to interface directly to computers
and other solid state devices.
