Cord switch and pressure sensor

摘要

A highly reliable cord switch the turn-on/off which can be recognized, from which malfunctions can be eliminated by preventing the electrodes from coming into contact with each other when they are bent, and which detects the pressure applied to the switch from all directions. By spirally arranging at least two electrode wires along the internal surface of a hollow insulator made of elastic rubber or elastic plastic in such a way that the electrode wires do not electrically come into contact with each other and are fixed to the hollow insulator projectingly from the insulator.
