である。2. Description of the Related Art Conventionally, there is known a pressure-sensitive sensor type cord switch which is deformed by receiving a pressure from the outside and a pair of conductive members arranged inside conducts electricity to detect the pressure. (For example, JP-A-6-26
This code switch is generally used as an entrapment prevention device for an automatic opening / closing door and the like, and electrically detects entrapment between a window frame and a window glass.

Is being detected. That is, a part of the elastic insulating member holding the conductive member is elastically bent by receiving a predetermined pressure, so that conduction between the conductive members is achieved.

る。On the other hand, a bridge conductor wire having a width that faces the pair of conductive members and bridges between the conductor members is provided, and a cord member having stretchability is provided while extending a support projection protruding toward the bridge conductor wire side. A cord switch covered with an elastic insulating member has been proposed (for example, Japanese Utility Model Laid-Open No. 7-7035). Also in this conventional technique, conduction between the conductive members is achieved by the buckling deformation of the cord member and the support projections provided on the cord member.

である。In both of the above-mentioned two conventional techniques, a part of the elastic insulating member is deformed by bending (bending deformation or compression deformation) so that the conductive members are electrically connected to each other.

When used as a device to prevent trapping of power windows,
Depending on the direction of the pressure applied to the cord switch, that is, the angle of the object sandwiched between the window frame and the window glass with respect to the cord switch (sandwich angle), buckling deformation of the elastic insulating member is insufficient and the sandwiching is ensured. It has the drawback that it cannot be detected.

Since the pinch cannot be detected unless the pair of conductive members both contact the bridge conductor, depending on the direction in which pressure is applied, one conductive member contacts the bridge conductor, while the other conductive member contacts the bridge conductor. It is not possible to detect the pinch.

Therefore, when the cord switch 30 is arranged in a vehicle window frame having a curved portion or a bent portion, for example, the conductive member 32, 34 when curved or bent by securing the space S by the protruding portion 36b. Inadvertent contact between them is prevented.
Moreover, when the cord switch 30 receives a predetermined pressure, the thin portion 36a is expanded and deformed while coming into contact with the tip of the protruding portion 36b, so that a wide detection range can be secured regardless of the direction of the applied pressure.
