Contact name the conductive path 17, the are arranged in the middle portion in the width direction of the intermediate portion 3B, similarly, the conductive path 21 is arranged in an intermediate portion in the width direction of the intermediate portion 3C.

  Further, on the distal end side of the intermediate portion 3B (on the side opposite to the proximal end portion 3A), the intermediate portion 3B has a predetermined width according to the form of the conduction path 17 branched and extended into the two. A distal end side portion 3D extending in a band shape is provided, and the intermediate portion 3B and the distal end side portion 3D are formed in a “T” shape as a whole. The distal end side portion 3D is an intermediate portion in the longitudinal direction of the distal end portion side portion 3D and is connected to the distal end portion of the intermediate portion 3B.

Similarly, a distal end portion 3E extending in a strip shape with a predetermined width is provided on the distal end side of the intermediate portion 3C. The conduction path 17 and the contact parts 13A and 13B are disposed in the intermediate portion in the width direction of the tip end side portion 3D. Similarly, the conduction path 21 and the contact parts 13C and 13D are also formed. These are disposed in the intermediate portion in the width direction of the distal end portion 3E.

  Further, the outer shapes of the spacer 5 and the film-like member 7 are formed in substantially the same manner as the outer shape of the film-like substrate 3. However, in order to expose the terminal portions 9 and 11, the spacer 5 and the film-like member 7 are not extended to the portions corresponding to the terminal portions 9 and 11, respectively.

In addition, the front-end | tip part side site | part of the said film-like member 7 corresponding to the site | part of the one end part side (side in which the contact part 13A is provided) of the front-end | tip part side site | part 3D of the said film-like base material 3 Corresponding to the intermediate part of the film-like member 7 corresponding to the intermediate part 3B of the material 3 and the one end part side (the side where the contact part 13C is provided) of the tip part side part 3E of the film-like base material 3 The third conduction path 23 is provided so as to extend in a “U” shape through the other tip side portion of the film-like member 7.

  That is, the first terminal portion 9 and the second terminal portion 11 are connected to a connector extending from another electrical device, and the first terminal portion 9 and the second terminal portion 11 are connected to each other. When a voltage is applied between them, the conduction paths 17 and 21 are disconnected on the tip side of the electrical resistance 19 (on the side opposite to the terminal sections 9 and 11 with respect to the electrical resistance 19) or the conduction path 23 , 25 even if the first terminal portion 9 and the second terminal portion 11 are connected to the electrical device, the first terminal portion 9 is connected via the electrical resistor 19. Since the current flows between the second terminal portion 11 and the second terminal portion 11, it can be easily determined whether or not each of the terminal portions 9 and 11 is connected to the other electric device.

  Therefore, for example, when assembling a vehicle on which a seat in which the switch device 1 is used is assembled, it is possible to prevent forgetting to connect the terminal portions 9 and 11 to the connector of the vehicle.

  Furthermore, since the electrical resistance is provided in the vicinity of the connector, it is possible to electrically monitor the disconnection of the connector of each seat. Therefore, the purchaser can grasp the abnormality in advance, avoid the possibility of using the system while the system is abnormal, and eliminate the possibility that the driver feels uncomfortable.

  In addition, since the electrical resistance is provided in the vicinity of the connector, even if the circuit ahead of the electrical resistance has any complicated shape (for example, a complicated branched shape), it depends on the complicated path shape. The operation can be confirmed without any problem.

Further, according to the switch device 1, the first and second contact portions 13 </ b> A to 13 </ b> D are provided on the film-like base material 3, and the third and fourth contact portions 15 </ b> A to 15 </ b> D are provided on the film-like member 7. Therefore, the distance between the first and second contact portions 13A to 13D and the third and fourth contact portions 15A to 15D is normally a space filled with gas. Blocked. Accordingly, first, second respective contact portions 13A to 13D, which is the third, fourth migration even moisture Shimii' into the space each contact portion 15A~15D is provided is less likely to occur .

  Further, according to the switch device 1, for example, the contact portion 13A in the first contact group and the contact portion 15A in the third contact group come into contact with each other and are electrically connected to each other, and the contact portions 13A and 15A are paired with each other. If the contact portion 13C in the second contact group and the contact portion 15C in the fourth contact group that are in contact with each other are not in contact with each other, the switch device 1 is not turned on, that is, the first, third The contact portions 13A and 15A that can be connected to each other in the contact group, and the contact portions 13C and 15C in the second and fourth contact groups that form a pair with the contact portions 13A and 15A come into contact with each other. Since the connection path is configured for the first time, malfunction of the switch device 1 can be prevented.

  Furthermore, by extending the conduction paths 17 and 21 so that they are separated from each other in the middle part of these extending directions, the contact parts 13A and 15A and the contact parts 13C and 15C are separated from each other. Since the AND circuit is formed, for example, even if the contact portion 13A and the contact portion 15A, which are one contact portion pair, come into contact with each other due to a sharp edge of the load, the other contact portion pair is used. Since the contact portion 13C and the contact portion 15C remain separated from each other, the switch device 1 is not turned on, and malfunction can be prevented.
