の接点部１２ａに押し付けられて接触する。Next, the operation will be described. First, when the shaft 2 is rotated, the driving body 6 fitted to the shaft 2 is rotated.
The rotating body 4 radially engaged with the convex portion 6c of the driving body 6 immediately rotates, and the conductor pattern portion 5 is brought into contact with the contact pieces 9, 10, and 11.
, A pulse signal is obtained, and the rotating body 4 rotates while performing a click operation. Next, when the shaft 2 is pressed in the axial direction, the driving body 6 is rotated without rotating the rotating body 4.
The protrusion 6c of the rubber member 1 extends along the recess 4d.
5 is deformed, and moves downward.
Moves to the lower wide recess 4d, and the movement is improved. Further, the rubber member 15 is pushed with the movement of the driving body 6, and the arm 14 b of the movable contact 14 is pushed by the rubber member 15, and the arm 14 b is moved to the first fixed contact 12.
And is contacted by being pressed against the contact portion 12a.

Is short-circuited and the switch is turned on. Also, movable contact 1
When the arm 14b of FIG. 4 is pressed down, as shown in FIG. 14, a lifting force in the direction of the arrow X acts on the joint, while the arm sinks in the direction of the arrow Y on the opposite side of the joint. The force starts to work. For this reason, since the annular portion 14a on the opposite side to the coupling portion is brought into contact with the fixed contact 13, strong contact is obtained. Further, since the convex portion 13e is provided on the contact portion 13a on the opposite side of the notch portion 13d, that is, on the opposite side of the joint portion, the fixed contact 13 on the annular portion 14a is provided.
The contact with is even stronger.

元に戻り、固定接点１２から離れた状態となる。Next, when the pressing pressure of the shaft 2 is released, the elasticity of the rubber member 15 causes the rubber member 15 to return to its original state. With this return force, the driving body 6 and the shaft 2 are pushed back to the original state. At this time, the convex portion 6c of the driving body 6 changes from the engaged state of the wide concave portion 4d to the engaged portion of the upper concave portion 4d. Therefore, the resistance is small at the initial movement of the return, and the return of the shaft is smooth. When returning, the vertical portion 6e of the convex portion 6c is in a state of being tightly fitted to the parallel portion above the concave portion 4d. Therefore, there is no backlash in the rotating direction and the radial direction, and the rotating body 4 can be driven by the nine moving bodies.
Further, the arm 14b of the movable contact 14 also returns to its original state due to its own spring property and is separated from the fixed contact 12.
