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.
Standard Characteristics/Ratings:
ELECTRICAL CIRCUIT: SPST-NO Double-break, SPST-NC
Double-break, and SPDT Double-break.
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.
ELECTRICAL RATINGS: (at 28 VDC or 115 VAC, 60/400 Hz.)
