ILLUMINATED ILLUMINATED & SEALED PUSHBUTTONS PUSHBUTTONS LP3 56 OTTO Full Line Catalog Specifications Subject To Change Without Notice 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 offhighway, 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 (25mÙ 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.
