RTS PT-400NL 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 10A, 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.
