PUSHBUTTONS

ILLUMINATED & SEALED PUSHBUTTONS

MOMENTARY ACTION COMMERCIAL GRADE LED ILLUMINATED & SEALED

The LP3 offers rugged, sealed construction with the added

benefit of reliable LED illumination.

The LP3 is a precision snap-action switch designed for use in off-

highway, material handling, industrial controls, marine, medical

and demanding commercial applications. Choose from the

standard mounting styles and electrical ratings, or contact us for

custom configurations.

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, amazingly low (25mΩ max, standard)

contact resistance and extremely low contact bounce are all

the result of the OTTO patented snap-action mechanism. Extra

long electrical life and precise trip point offer added value and

precision operation.
