Makes and breaks every time!
OTTO’s inherent rocking action
breaks, welds and wipes contacts clean.
The P8 series pushbutton switches feature a shortened
back 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
(25m max) and short contact bounce (5ms max) are the result
of 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 P8 is well suited to interface directly to
computers and other solid state devices.
The P8 series is a quality precision snap-action switch designed
for use in panel boards, control sticks, computers, instruments,
pressure switches and other hand or machine operated applications
where rugged pushbutton switches are required. In addition, its
precision permits the OTTO P8 to also be used as a limit switch.
The P8 offers unique size, high electrical ratings and a wide
choice of mounting styles.
