In this case, a coil spring ^ mounted in the spring mounting hole is contracted between the operation button and the support plate (23) so that the operation button always has a tendency to return. By the way, the operation button is normally a pressing hole ^ a

(2J) It faces the a and is surely guided into the window hole a during the pressing operation.

The configuration and mounting state of the other operation buttons ^ ~ are the same as above, with the operation button ^ on switch elements B and E, the operation button on switch elements F 'and C, and so on. The operation buttons β¾ correspond to the switch elements D and, respectively. As described above, each of the operation buttons ^ to ^ corresponds to two switch elements.

Each engaging claw is attached to the specific center (7), that is, the shaft bin (l) e.

^ c ~ (¾k) A crown-shaped intersect with a cam (27) a is freely mounted. Fig. 19 As shown in Fig. 21, a serrated cam is attached. The surface (27) a has five teeth as an example of a number different from the four operation buttons ^ -e¾, in other words, four engagement claws ^ c-e¾c. As shown in Fig. 20, the chevron section of each tooth that forms each tooth is not of the target shape on both sides, centering on the ridge line (crest). When viewed in a plane, each chevron formed at an opening angle of 72 ° is centered on the ridgeline.

The number of teeth on the serrated cam surface ^ a is not limited to five as described above, but is three, seven, or nine. If so, another number may be used.

Therefore, as shown in Fig. 10, there are four engaging claws.

When one engagement claw ^ c is located facing the innermost part of the valley, all other engaging claws ^ c to e¾c face parts other than the innermost part of the valley. Then, when the engaging claw is pushed all the way to the deepest part of the valley, only the switch elements (two) corresponding to this operation button are exclusively turned on and each of the switch elements A to Simultaneous activation of F 'is prevented.

Next, FIGS. 22 to 27 show a third embodiment of the original invention. This embodiment is different from the first and second embodiments mainly in the configuration of the movable contact portion in each switch element. In other words, a cushion section having a new mountain shape having elasticity is provided on the fixed contact structure, and the movable contact is fixed inside the top of the cushion section. Therefore, the movable contact point is different from that of the first and second embodiments in that the movable contact point can be formed by a single metal piece.
