Support members are provided on the terminal portions of a sensor main body. In this state, a seal portion is formed by molding, and the seal portion seals the terminal portions of the sensor main body. During molding, external pressure acts on a housing. However, since four electrode wires pulled out from the housing are supported by insulating support members, the four electrode wires do not contact one another due to the pressure applied during molding, and thus do not short-circuit.

Method for manufacturing a pressure sensitive sensor

In order to provide a cord switch which can securely catch the ON/OFF operations, can cancel an erroneous operation by preventing the contact between electrodes caused by bending of the cord switch, and have a positive sensibility for the pressurization in all directions and a high reliability, at least two wire electrodes are spirally arranged along the inner surface of an insulator which is hollowed in the cross section and comprises a restorative rubber or plastic material in the longitudinal direction in a situation where the wire electrodes are not electrically contacted each other, and the wire electrodes are fixed to the hollowed insulator in a state where the wire electrodes are projected from the insulator.
