Are tilted with two corresponding points of the support protrusion 1f in the storage portion 1a provided on the tilted side as fulcrums.
At this time, the pressing surface portion 6d provided outside the rotating body 6 presses the support surface portion 8c of the base 8a of the second slide member 8, whereby the second slide member 8 The arm portion 8b is bent at two corresponding points of the support protrusion 1f in the storage portion 1a as a fulcrum, and the peripheral contact portions located in four directions around the circuit board 10 are arranged. When the contact 11b is pressed, the dome-shaped movable contact 11d is inverted and connected to the fixed contact 11c, and the switch is turned on.

At this time, the second slide member 8 is connected to the first slide member 3 via the rotating body 6, and the second slide member 8
Does not follow when the first slide member 3 and the rotating body 6 are operated to rotate, but follows when the first slide member 3 and the rotating body 6 are operated to tilt, so that the four directions around Is pressed against the peripheral contact portion 11b. When the pressing in the tilting direction is released from this state, the rotating member 6 and the first rotating member 6 are moved by the spring property of the arm portion 8b of the second sliding member 8.
Is returned to the initial position.

Accordingly, there is no need to separately provide a spring for returning the second slide member 8 and the rotating body 6, and the configuration is simplified. Further, the storage portion 1a of the housing 1
A plurality of the support protrusions 1f are formed on the inner bottom surface of the support protrusion 1f to abut on the lower surface of the arm portion 8b and position the second slide member 8 in the storage portion 1a.
Since the arm portion 8b is bent around the fulcrum f, the spring property of the arm portion 8b is reinforced, and the second
The return of the slide member 8 and the rotator 6 is assured.
