Shows a state in which the center is cross-sectioned from the portion excluding the electrode projection 3c. First, the state where no pressing force is applied (Fig.
(a) and FIG. 5), the bowl-shaped raised portion 3a of the movable contact piece 3 is curved upward, and the bowl-shaped raised portion 3a
The upper surface of is in contact with the peripheral edge of the hole 1a in the electrode plate 1.

Finally, as shown in FIG. 4A, the insulating surface 3c contacts the fixed contact piece 5. On the other hand, the electrode projection 3b of the movable contact piece 3 is reversed as a reaction of the downward displacement of the bowl-shaped raised portion 3a, and is displaced upward to separate from the fixed contact piece 5.

ととなる。As described above, since the push switch of the present invention is turned off when the pressing force is applied and is turned on when the pressing force is released, it can be used as an antitheft device for a work of art. Due to the weight of the switch, the switch is in the off state, and the removal of this art work causes the switch to be in the on state to drive the alarm device.

(For example, when used outdoors or underwater), there is no risk of breakdown,
In addition, by accommodating the movable contact piece in the hole of the insulating plate, the assembly of the switch becomes extremely easy, the displacement of the movable contact piece is prevented, and there is an effect that it can sufficiently withstand long-term use. Is.
