SHORTER BEHIND PANEL, SUBMINIATURE DOUBLE-BREAK, SNAP-ACTION

Makes and breaks every time!

OTTO’s inherent rocking-action

breaks welds and wipes contacts clean.

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 (120 grams), low contact resistance (25

milliohms) and short contact bounce (5 milliseconds 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 plated) configuration

the P8 is well suited to interface directly to computers and other

solid state devices.

The OTTO 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.

Standard Characteristics/Ratings:

Electrical Circuit:

Because the OTTO P8 is a double-break, two-circuit switch, it can operate

as a single or two circuit device. Thus, a wide variety of connection possibilities are available.

See “Circuit Form” in part number code for options. Special variations can be provided.
