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 force (120g/4.2 oz), low contact resistance (25mΩ
max) and short contact bounce are the result of our snap-action
mechanism. These characteristics guarantee exceptional
current carrying capabilities over the life of the switch. With the
optional low level 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.
