NKK Switches High Security Keylock CKL12BFW01-005

The CKL series high-security keylock is a 19mm bushing-mounted switch with a flat key, rated for 3A at 250V AC resistive load. It features a break-before-make contact timing, 90° angle of throw for two-position operation, and silver-plated copper contacts. The housing is zinc alloy with chrome plating, and the base is made of LCP. Operating temperature ranges from -25°C to +70°C. Mechanical life is 30,000 cycles minimum, and electrical life is 10,000 cycles minimum. Contact resistance is 20 milliohms maximum, insulation resistance is 1,000 megohms minimum at 500V DC, and dielectric strength is 1,500V AC between contacts and case for one minute. Mounting torque is 1.5 Nm maximum. Solder lug terminals are epoxy sealed. The switch is designed for high security applications with a rugged die-cast housing and self-cleaning sliding contacts.
