Two electrically-independent 2-conductor fingers in a black handle. Can be used with single or dual cables for independent tip circuits with common sleeve or separate sleeve circuits.
Miniature telephone twin plugs with two 2-conductor or two 3-conductor fingers, designed to mate with TT Twin-Jax, TT-Jax, and other phone jacks with a .176" inside diameter bushing and compatible tip and ring springs. Approximately 1/2 the size of standard phone plugs; yet retains uniformity, dependability of high-quality phone plugs. The phone plugs are exceptionally light, small and rugged. Plug fingers can easily be removed and replaced.
Minimum Space: Plugs fit .313" centers, horizontally or vertically.
Self-Aligning: Plug fingers compensate for minor variations in jack spacing.
Polarizing: Handle notches identify location of each finger.
Tip Monitoring: Handle ports permit probe insertion to monitor tip circuits.
Terminating and Looping Plugs: OEMs can fabricate cross-wired plugs, i.e., tip-to-sleeve, tip-to-ring, etc., according to individual requirements. OEMs can also wire-in resistors, RCL networks, etc. for standard and special terminating applications. Switchcraft will build looping and terminating TT-Twin Plugs on special order, where quantities warrant.
Sleeve Plugs: For looping, terminating and single cable applications, sleeve plugs seal off unused handle opening(s). Sleeve plugs also make a bridged (common) sleeve connection by holding braided shield in place in second plug.On special order, TT-Twin Plugs can be supplied with one 2-conductor finger and one 3-conductor finger.
Ease of Assembly/Disassembly: Refer to illustration below for assembly/disassembly procedure; no handle retaining screws required. Tip and ring terminations are screw-type screws supplied).
DISASSEMBLY: Place plug on edge as shown. Push down and back on metal lip on finger (inside notch) with small screwdriver and slip plug finger out of handle. Turn plug over and repeat for other finger. 2. CABLE I
NSTALLATION: Fold braided shield on cable back over insulation. Insert leads through rear of plug finger, and screw finger (clockwise) onto cable with twisting motion until lead terminations lineup with threaded tip and/or ring openings. Fasten terminals on both fingers with screws provided.
To bridge sleeves (common connection), place free end of braided shield in remaining finger sleeve opening. Press sleeve plug firmly in place.
