NKK Switches High Security Keylock CKL12ATW01-032

The CKL series consists of 19mm diameter high-security keylocks with a zinc alloy, chrome-plated housing, designed for higher security applications. These switches feature a vertically rotating mechanism with self-cleaning sliding contacts, a 90° angle of throw, and an electrical capacity of 3A at 250V AC resistive load. 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. The housing is sealed with epoxy-coated terminals, and the switch operates reliably across a temperature range of -25°C to +70°C. Mounting is via a 19mm hex nut, with a maximum mounting torque of 1.5 Nm. Keys are brass with chrome plating for flat key variants and nickel plating for tubular keys. Mechanical life is 30,000 cycles minimum, and electrical life is 10,000 cycles minimum.
