VANDAL RESISTANT PUSHBUTTONS
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 force (120g/4.2 oz), low contact resistance
(25mΩ) and short contact bounce (5ms max) are all a result
of our 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.
