Next, the operation of the above-described switch device will be described with reference to FIG.
6 through FIG. As shown in FIGS. 1 and 2, in the initial state, the conductor plate 8 is in a state where the first movable side contact 9 is separated from the first fixed side contact 2 a by a predetermined distance. It is off. In this state, the conductor plate 8 is urged by the urging force of the reversing coil spring 10 in a direction (upward) opposite to the peripheral terminals 2 and the first fixed contact 2a. The second movable side contact 12 and the second fixed side contact 4a are also separated at a fixed interval, and the contacts are in an off state.

At this time, the locking portion between the conductor plate 8 and the reversing coil spring 10 exceeds the locking portion between the support arm 7 and the central terminal 3 (the locking portion of the support plate locking projection 3a). And the direction of the biasing force of the reversing coil spring 10 is reversed upward, and the conductor plate 8 self-runs on the side opposite to the inner bottom surface of the first storage portion 1b, and the first movable side contact 9 is separated from the first fixed contact 2a to turn off the contact, and the second movable contact 12 is also separated from the second fixed contact 4a, 4a to turn off the contact. , And returns to the initial state shown in FIGS.

According to the above-described embodiment of the present invention, the second movable contact 12 composed of a torsion coil spring is used as the contact of the detection switch for switching the DC power supply on the secondary side. Therefore, the configuration of the detection switch unit can be simplified, the size and cost can be reduced, and the handling of the torsion coil spring is easy and difficult to deform, so that the workability of assembly is improved. .

Further, the contact points of the power switch for switching the AC power on the primary side and the detection switch for switching the DC power on the secondary side are built in the same case 1 and movably housed in the case 1. The second movable contact portion 12 and the second fixed contact portion 4a of the detection switch are formed on the lower surface of the slide member 11 opposite to the upper surface on which the lock cam is formed. Thus, by effectively utilizing the dead space on the lower surface side of the slide member 11, the outer shape of the switch device can be reduced, and the cost can be reduced. The strength and on-position accuracy can be improved.

In the above-described embodiment, the fixed terminal 4 and the second fixed contact 4a of the detection switch are formed by a metal plate of a conductor. However, instead of this, they are formed by a conductor wire. In this case, the material cost is reduced, and the cost can be further reduced.

Further, the second movable contact 12 composed of a torsion coil spring of a detection switch is connected to the slide member 11.
The guide portion 11g formed on the lower surface side of the case 1, but instead of this, the second storage portion 1 of the case 1
The guide portion 11g may be formed on the inner bottom surface of the second contact c to lock the second movable contact 12, and in this case, the same effect as the above-described configuration can be obtained. is there.
