The spring member 18 and the tongue-like portion 20 bend downward while maintaining the distance d, and when they eventually move by a distance c+s, the contact point of the microswitch 22 is closed. At this time, b is selected to be larger than c+s, so when the contact of the micro switch 22 is closed, the operating member 10 is still connected to the protrusion 12,
12, 14 and the operating member 10 is still pressed down. At this time, the tongue portion 20 is in contact with the microswitch 22 and cannot be lowered any further, so the distance between the spring member 18 and the tongue portion 20 is only shortened. Furthermore, d is b
Since the spring member 1 is selected to have a larger size, the spring member 1
8 does not come into contact with the tongue-shaped portion 20. Therefore, before the operating portion 10 contacts the protrusions 12, 12, 14, the spring member 18 contacts the tongue portion 20,
The micro switch 22 will not be damaged due to unnecessary force being applied to it. In addition, in this way, the spring member 18
The strength of the spring member 18 is selected to allow movement of the spring member 18.

を押し下げても、同様である。 When one of the edges of the raised portion of the operating member 10 is pressed down, for example the part marked A in FIG.
The portion A descends using the opposite position across the center as a fulcrum until the edge of the operating member 10 comes into contact with the protrusion 14 . At this time, the moving distance of the rod-shaped member 16 is approximately b/2. This is because the rod-shaped member 16 is located approximately in the center between portions A and B. Here, since b/2 is selected to be larger than c+s, the microswitch 22 can be closed. This is the same no matter which edge of the raised portion of the operating member 10 is pressed down.
