いても言及されていなかつた。As described in Japanese Utility Model Publication No. Sho 53-28051 and Japanese Unexamined Patent Publication No. Sho 58-31875, a conventional illuminated push button switch is provided with a return spring for an operation button and a contact contact mechanism at a central portion immediately below the button. Therefore, no consideration has been given to the restoring force against the inability to return (fixed) due to the corner pressing of the operation button and the certainty of the contact contact operation due to the corner pressing. Also, in the illuminated push button switch shown in Japanese Utility Model Publication No. 56-147533,
Since the leaf-spring-like movable contact mechanism is disposed at one position below the button, the reliability and reliability of the contact contact operation by corner pressing have not been discussed. This type of push button switch does not have an escape mechanism for excessive operation pressure of the button, and the operation pressure is transmitted directly to the contact mechanism of the contact, so the movable contact breaks beyond the elastic limit of the contact. Or
No mention was made of defects such as premature wear or abnormal wear of the contacts.

いる。In FIG. 4, when the corner P of the button 3 is pressed, the button 3 rotates counterclockwise around the point B by overcoming the reaction force of the return spring 2, and the lower part 3 'of the button 3 Try to contact. However, the lower part 3 'of the button 3 is a printed board in the turning process.
Before touching 41, the button frame 3 and the button 3 come into contact, and this contact point
Since there is a three-point contact between B, C and D, if there is a sharp projection or burr on the button 3 side at point B, the button 3 will be caught and the button 3
Was not restored. This problem is because the return spring is located at one place in the center of the button,
The reason is that the restoring force does not act sufficiently during heavy traffic.

た。FIG. 5 shows the engagement state of the button frame 1 and the button 3 in FIG.
In the cross-sectional view taken along the line V, the four corners 3 "of the button 3 always contact one of the four corners 1" of the button frame 1 at the time of pressing the corner, so that an extra trapping phenomenon is induced and a return occurs. This was the cause of the disability. This hard-to-return phenomenon is related to call registration when a passenger gets on the elevator car and presses the desired destination floor button, stays on without being turned off even after arriving at the floor and getting off. Not
There is always a problem that wasteful power is consumed to drive to the same floor, and furthermore, the hall button on the side of the hall indicates that after the elevator arrives at that floor, the elevator remains stopped at that floor. There was a problem that service was not provided.

サービス低下であつた。In addition, since the contact mechanism portions 5 and 7 of the contacts are also arranged at one position in the center of the button, there is a problem that when the corner is pressed, the light emitting element 8 is not displayed as a response due to poor contact sometimes. Therefore, the problem that the response is not displayed unless the button 3 is operated and pressed substantially at the center is a remarkable decrease in service for passengers.

Since the contact is directly transmitted to the contact mechanism of the contact, it leads to premature wear and abnormal wear of the contact, so that the expected life of the illuminated push button switch of the elevator cannot be achieved.

早期摩耗や異常摩耗を防止するものである。The object of the present invention is to provide return springs for the buttons at the four corners of the buttons, and to provide a plurality of sets of contact mechanisms for contacts for performing contact display by pressing the buttons and displaying the response of the light emitting element in parallel within the push buttons. Is achieved by: Further, in the contact mechanism of the contact, the movable contact to which the fixed contact is bridged is a finger mechanism made of a plate-like elastic body, and further, by engaging an “escape spring” on the finger mechanism, the contact portion is formed. It prevents early wear and abnormal wear of the steel.

上の負担を与えない構造とする。That is, by providing the return springs of the buttons at the four corners of the buttons, the inability of the buttons to return due to the excessive inclination of the buttons when pressing the corners is prevented by the return force of each return spring. A contact contact mechanism for displaying a response of a light emitting element contacted by a button pressing operation is provided near each of the four lower corners of the projection of the button, and these are connected in parallel to each other so that a contact can be made when the corner is pressed. By preventing the associated contact failure, even if any part of the button is pressed, the button can be reliably operated and responded. In order to prevent early wear or abnormal wear of the contact due to excessive operation pressing of the button, the movable contact is temporarily fixed to the fixed contact so that the operation pressing of the button is not directly transmitted to the contact mechanism of the contact. After the contact, a relief force is generated by the relief spring, so that the movable contact and the fixed contact are not subjected to a load exceeding a specified value.
