NKK Switches High Security Keylock CKM13ETW01

The CKM13ETW01 is a 16mm diameter, tubular key-operated high security keylock with a SPDT ON-OFF-ON circuit, silver contacts, and solder lug terminals. It has a power rating of 3A at 250V AC, a contact resistance of 20 milliohms maximum, and an insulation resistance of 1,000 megohms minimum at 500V DC. The switch withstands 15 kilovolts electrostatic discharge and has a dielectric strength of 1,500V AC between contacts and case. Mechanical life exceeds 30,000 cycles and electrical life exceeds 10,000 cycles. The housing is glass fiber reinforced PBT, the key is brass with nickel plating, and the contact terminals are copper with silver plating. Operating temperature ranges from -25°C to +70°C. The angle of throw is 90° for positions 1 and 3. Mounting torque is 1.5 Nm maximum. The switch incorporates a push-and-lock mechanism for key-removable operation and is epoxy sealed for contamination protection.
