This is a modern, new, black, "G" style handset (such as used on 500 and 2500 sets) with a push to talk switch and a 4 wire cord with spade lugs.  We recommend this style of handset for use on layout phone systems because an operator can pick up the handset and listen without adding background noise into the circuit.  The user pushes the bar inside the handset to engage the transmitter.  These handsets are equipped with 9' coil cords.  

See our application notes or Seth Neumann's "Communications for Model Railroad Operations" clinic for information on how to connect these handsets.

We can supply these handsets for you in different color and cord configurations if desired, please contact us. We also have used PTT Handsets in many colors and configurations (Carbon/Dynamic mics, different wiring options), again please contact us with your requirements for a quotation.
