NKK Switches High Security Keylock CKL12ATW01-033

The CKL series is a high-security keylock with a 19mm bushing, designed for applications requiring elevated security. It features a brass tubular or chrome-plated flat key, a zinc alloy housing with chrome plating, and LCP base. The switch has a 3A resistive load rating at 250V AC, 10,000 electrical cycles minimum, 30,000 mechanical cycles minimum, and a dielectric strength of 1,500V AC between contacts and case. Contact resistance is 20 milliohms maximum, with insulation resistance of 1,000 megohms minimum. The operating temperature range is -25°C to +70°C, and it withstands 30G shock and vibration per specified parameters. Mounting torque is 1.5 Nm maximum. The switch is epoxy sealed, has a break-before-make contact timing, and a 90° angle of throw. Terminals are solder lugs with silver-plated copper. The model supports SPDT ON-NONE-ON circuitry with key removal in position 1, and is designed for panel mounting with a 19mm hex nut included.
