As a contact switch for detecting contact with an object, for example, a pressure-sensitive switch 20 as shown in FIG. 5 is used. This pressure-sensitive switch 20
A pair of strip-shaped electrodes 22a and 22b are attached to the inner wall of one insulating film 21 bent in a cylindrical shape so as to face each other with a predetermined gap therebetween. Usually, the pair of strip electrodes 22a and 22b are off when the pair of strip electrodes 22a and 22b are not in contact with each other. When a pressure is applied and the strip-shaped electrode 22a and the strip-shaped electrode 22b come into contact with each other, the switch is turned on to detect the pressure.

けても、同様の効果が得られる。FIG. 2A is a diagram showing an example in which the pressure-sensitive switch 10 is used as a door-end switch.
The pressure-sensitive switch 10 is mounted so that one piece (hereinafter, referred to as a horizontal piece) 10a abuts on each of the opposing surfaces 24K, 24K. At this time, the pieces 10b perpendicular to the horizontal piece 10a (hereinafter, referred to as vertical pieces) 10b are not opposed to each other, that is, when the door 24 is closed, the vertical piece 10b of one pressure-sensitive switch 10 is As if pressing the horizontal piece 10a of the pressure-sensitive switch 10,
Two pressure sensitive switches 10, 10 are mounted. Thus, when the door 24 is closed, the two pressure-sensitive switches 1
Since the horizontal pieces 10a and 10a and the vertical pieces 10b and 10b that constitute 0 and 10 are both pressed, the strip electrodes 11a and 11b can be reliably brought into contact with each other. Therefore, a highly reliable door switch free from malfunction can be obtained. Note that FIG.
As shown in (b), the two pressure-sensitive switches 10, 10
The same effect can be obtained even if the fins are attached such that the bent portions 10c face each other.

めることができる。Since the pressure-sensitive switch 10 is provided over substantially the entire length of the contact portion of the door 24, the length of the pressure-sensitive switch 10 is usually about 1.8 m. Since the conductive silicone rubber forming the strip electrodes 11a and 11b has an electric resistance of about several Ω to several tens Ω per 1 cm, the resistance value between the two electrodes when the strip electrodes 11a and 11b are conductive depends on the contact state. It has a variation of about several Ω to several KΩ. Therefore, in the present embodiment, each of the strip electrodes 11a, 1
A conductive wire 13 is buried in the center of 1b along its longitudinal direction so that the resistance value between the two electrodes is less fluctuated by the contact position of the pressure-sensitive switch 10. For example, even when the two pressure-sensitive switches 10 and 10 are in contact only at the thick line portion Z shown in FIG. 3A, the resistance between the two electrodes is extremely small because of the presence of the conductive wire 13. Becomes FIG. 3B is a schematic diagram of an equivalent circuit in the contact state, in which the conductive wire 13 and the strip electrodes 11a and 11b are shown.
And the resistance R13 of the conductive wire 13 is negligible with respect to the resistance R10 of the conductive silicone rubber, so the resistance between the two electrodes is The resistance is substantially equal to the resistance r of the conductive silicone rubber constituting the contact portion, and the value is an extremely small value of 100Ω or less. Therefore, the pressure-sensitive switch 1
A stable conduction resistance can be obtained regardless of the contact state of 0, that is, the pressed state, so that the reliability of the door switch can be further enhanced.

Since the conductive wire 13 extending in the length direction of 1b is embedded, the strip electrode 11a and the strip electrode 11b can be reliably brought into contact with each other, and the pressure-sensitive switch 10 having high sensitivity regardless of the pressed state is obtained.

The pressure-sensitive switch 10 of the present invention can be used alone, such as the contact switch shown in the above-mentioned conventional example. FIG. 4 shows an example in which the pressure-sensitive switch 10 is installed at the corner of a pillar 25. Since the pressure-sensitive switch 10 of the present invention has a substantially L-shaped cross section, the corner of an automatic guided vehicle or a robot, Suitable for installation in corners of obstacles such as pillars and walls. In addition, even when pressure is applied to a position off the center of the insulating sheet 12, the strip electrodes 11a and 11b can be reliably brought into contact with each other, so that the sensitivity is improved.
