High insulating material for 16mm CKM models withstands
over 15 kilovolts of electrostatic discharge, thus providing
antistatic feature.
Rugged, die cast housing 19mm CKL models designed for
higher security requirements.
Vertically rotating switching mechanism combines with
self-cleaning sliding contacts for high reliability and
long operating life.
16mm and 19mm diameter bushings available.
CKL and CKM on-off-on models with tubular keys have
push-and-lock mechanism which allows contactor to drop
and slide over stationary contacts.
Available in both flat and tubular key styles; flat key is
reversible for easier setting.
Epoxy sealed terminals prevent entry of flux and other
contaminants.
Interior construction provides seal for contact area.
High dielectric strength of 1,500 volts between contacts
and case.
