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 (25m 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.
