COMMERCIAL GRADE LED LIGHTED AND SEALED AGAINST DUST AND MOISTURE
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 (25 milliohms maximum, 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.
