ラのスイツチの改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a camera switch suitable for a display switch in which electrical conduction and non-conduction between electrodes are effected using conductive rubber.

いと云う恐れがあつた。 As for this type of switch, the present applicant previously placed a pressurized conductive rubber layer between the switch member and the electrode substrate, and pressed the switch member with a finger to press the pressurized conductive rubber layer to make it conductive. We proposed a switch that conducts current between the electrodes, releases the pressure of the switch member, and disconnects the current through the restoring force of the pressurized conductive rubber layer (Utility Application No. 53-81240). However, with the switch of this earlier application, there is no problem if the pressurized conductive rubber layer has sufficient elasticity, but if the elasticity is insufficient due to the shape and material of this rubber layer, the switch member may not be pressed. Even after release, the pressurized conductive rubber layer could not completely return to its original position, and there was a fear that it would not become electrically conductive.

供することである。 Therefore, the purpose of this invention is to improve conduction between electrodes,
An object of the present invention is to provide a camera switch that can reliably turn off conduction.
以下にこの考案の一実施例に係るカメラのスイ

に接し、これらの電気的接続を果す。 In FIG. 1, reference numeral 1 designates a release button, which is a known button that, when pressed, causes a predetermined shutter release operation to be performed via a release rod 2 provided below. This release button 1
is movably provided in a cylindrical release button seat 3, and on the lower surface of the flange of this button seat 3, a plurality of protrusions 4 arranged in the circumferential direction with a predetermined interval from each other are arranged to support the switch member. It is formed as. Below this flange part, as shown in detail in FIG.
Further, insulating electrode substrates 7 are successively arranged concentrically. The separator 6 is made of an insulator such as synthetic resin, and has a plurality of openings 6a formed at predetermined intervals in the circumferential direction. These openings 6a are provided through the conductive rubber layer 5 in correspondence with the projections 4, and when the projection 4 locally pressurizes the conductive rubber layer 5, a portion of the rubber layer 5 passes through the openings 6a. is pressed elastically downward,
It is designed to come into contact with the upper surface of the electrode substrate 7.
A pair of electrodes 8a and 8b are printed on the upper surface of the electrode substrate 7 at a predetermined distance from each other, and the portion of the conductive rubber layer 5 pressed through the opening 6a is connected to the electrodes 8a and 8b. , 8b are in contact with each other on top to achieve electrical connection between them.

導通が確実となる。 In the camera switch configured as described above, when the release button seat 3 is pressed, the conductive rubber layer 5 is locally pressed through the switch member 4 as described above, thereby establishing electrical continuity between the electrodes 8a and 8b. When the pressure on the button seat 3 is released, the elastic force of the conductive rubber layer 5 causes the switch member 4 to return to its original position, and the electrodes 8a and 8b become non-conductive. As a result, even if the conductive rubber layer 5 does not have sufficient elasticity,
Since the conductive rubber layer 5 is locally deformed and restored by the action of the separator 6, conduction and non-conduction between the electrodes is ensured.

戻り非導通となる。 Figures 3 and 4 show an example of this.
The conductive rubber layer 5 has the shape shown in the figure. That is, the lower surface peripheral edge portion 5a of the conductive rubber layer 5 extends below the central portion 5b, and an annular groove 5c is formed between these portions on the lower surface. As a result, the conductive rubber layer 5 has its peripheral edge 5a in contact with the peripheral edge of the electrode substrate 7, and its central portion 5b is connected to the pair of electrodes 8.
It is located above between a and 8b with a predetermined distance therebetween. When the release button seat 3 (which serves as a switch member since no protrusion is formed on it) is pressed, the peripheral edge 5a of the conductive rubber layer 5 is deformed, and the center portion 5b is connected to the electrode 8a, 8b
Contact between them to establish continuity. Then, when the pressure is released, the restoring force of the peripheral edge portion 5a returns to the original state and becomes non-conductive.

This switch may be provided anywhere on the outer surface of the camera as long as it can be pressed by a finger or the like. As an example, in FIG. 5, it is provided on the peripheral wall of the camera, and it can also be provided on the side surface 11 of the camera surface, the right front plate 12, the left front plate 13, the back cover (not shown), etc. can.

し、非導通とすることができる。 As explained above, the camera switch according to this invention is usually separated from both electrodes of the conductive rubber layer by an isolation member, and the conductive rubber layer is deformed by pressing the release button seat and brought into contact with the electrodes. Even if the conductive rubber layer does not have a strong elastic force, it will surely return to its original position and become non-conductive when the pressure on the release button seat is released. .
