The Telex® PT-400 switch kit connects in-line in the cordage of a headphone or microphone. It may be wired to provide a variety of functions such as push-to-talk, push-to-cough or relay keying when used with Ham, CB, and other communications equipment. The kit contains either one or two SPDT Type, Form C, micro switches rated at 10 amps, 125/250 VDC. The switches are positively mounted over two spring pins inside the high impact plastic housings. Two vinyl strain/bend reliefs along with two metal retainers hold cordages up to 0.18" (4.6mm) in diameter firmly in place. The high impact plastic pushbutton can activate the switches to either a momentary or a locked "on" position. A clothing/belt clip is firmly attached to one of the housing halves. The clip can be rotated 360° to locate the switch assembly in any convenient position.
