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. F 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. Actual Size CKM with Tubular Key Interior construction provides seal for contact area. High dielectric strength of 1,500 volts between contacts and case.
