Incidentally, the external electric wires A, C, L, and T are respectively arranged in the container body 2 by terminal screws 10, as shown in FIG.

Next, the operation of this embodiment will be explained.

The emergency push button switch according to this embodiment is as follows:
As shown in Fig. 4, attach it to the surface of the construction material with the arrow direction facing upward.

On the surface of the lid body 3 are the words "Press strongly" to indicate the operation of the protective cover 11, the words "Emergency alarm" to clearly indicate the function of the light emitting diode 27, and the words "Press strongly" to clearly indicate the operation result of the micro recess 26. The words "Recovery" are displayed on each page.

Assuming that an emergency situation has occurred, if you press the protective cover 11 with your finger, a pressing force will be applied to the actuating rod 16, but the engaging portion 23 of the release button 22 will not engage with the protrusion 21 of the actuating rod 16. Therefore, the actuating rod 16 does not swing until the pressing force becomes greater than this engagement force. That is, the operating rod 16 does not operate until the pressing force of the protective cover 11 exceeds the resistance force obtained by adding the urging force of the first spring 13 and the urging force of the release button 22, thereby preventing the switch mechanism from malfunctioning. Ru.

When the pressing force exceeds a certain level, the protrusion 21 of the actuating rod 16 comes off the release button 22, the protective cover 11 moves together with the actuating rod 16, and the push button 14 pushes the leaf spring 8 to bring the contact 9 into contact with the terminal 7. A closed circuit with external wires is formed. This causes emergency equipment (not shown), such as sprinklers, to operate.

On the other hand, since the protrusion 21 of the operating rod 16 enters the back side of the release button 22 in the above state, even if the pressing force of the protective cover 11 is released, the switch mechanism does not return to its original state, and the switch operating state is ensured. Ru. If you want to restore this, press the release button 2.
The second minute recess 26 is moved in the direction of arrow D so that the actuating rod 16 and the protective cover 11 are pushed back by the urging force of the switch spring 15. This opens the circuit and puts it into a non-conducting state.

In this case, when a closed circuit is formed by the movement of the actuating rod 16 and the like, the external wires A, C, and L become conductive, and current flows through the light emitting diode 28, causing it to emit light. Since this light emitting diode 28 is exposed on the surface of the lid 3, it clearly indicates that the emergency push button switch is in operation.

Furthermore, when the jack 33 is inserted into the jack hole 32, the leaf springs 40 and 41 in the free state come into contact with the corresponding conductor parts 33a and 33b of the jack 33, respectively.
Conducted with TC. If the jack 33 is a jack for a telephone, the telephone becomes usable and the operating status of the emergency push button switch can be communicated to a predetermined department.

In the above embodiment, a light emitting display was used as the emergency alarm display means, but the present invention is not limited to this, and other means for displaying an alarm that the emergency push button switch is in operation may be used. For example, it may be a sound, a flashing light, etc. Further, the structure, arrangement, etc. of the jack holes are not limited to the above embodiments.

[Effects of the Invention] As explained above, according to the present invention, since the switch mechanism, the emergency alarm display means, and the jack hole are provided in the main body of the device, it is possible to It can be easily installed without requiring any special construction work, and its sleek appearance makes it suitable for use not only in buildings and other public buildings, but also in ordinary homes.
