Use this switch wherever on/off power control is desired. It may be used on either 12 or 115 volt lines with zip type cords between 16 and 20 gauge. No soldering, only a screwdriver and wire cutter are required for assembly. To connect, disassemble the switch, cut a segment from one conductor, install wires in the switch, and reassemble. Sharp teeth inside the switch make the necessary electrical contacts. This is the same switch as used on the CK1008 series of lead-in wires. Measures 1-1/4" by 5/8".
