Further, in the switch device of the present invention in this embodiment, since the earth side fixed contact 6 and the power source side fixed contact 7 are vertically and horizontally symmetrical plate-shaped, the earth side fixed contact 6 and the power source side fixed When the contact 7 is assembled in the holder 2, even if the earth side fixed contact 6 and the power supply side fixed contact 7 are out of phase and 90 degrees out of phase with each other, there is a possibility that the electric circuit may be hindered. There is no.

Furthermore, in the switch device of the present invention in this embodiment, as shown by the chain double-dashed line in FIG. 7, the push plate 3 is provided with the cover portion 32 for covering the guide 19 and the actuators 41 to 44. ,
It is possible to prevent water from entering the inside of the switch device from between the guide 19 and the actuators 41 to 44.

Although the two-way switch device 8 is incorporated in the above-mentioned embodiment, the two-way switch device 8 may be used only in the four-way switch device without being incorporated.
