点２２上に位置する。Operation When the switch lever 5 is rotated to the low position,
Each of the movable contacts 15 to 17 corresponds to points 15' to 1 in FIG.
7', and the low fixed contact 18 and the common fixed contact 22 are electrically connected. When the switch lever 5 is rotated to the middle position, each movable contact 15 to 17 moves to point 1.
5'' to 17'', and the middle fixed contact 19 and the common fixed contact 22 are electrically connected. When the switch lever 5 is rotated to the high position, each movable contact 15 to 17
are located at points 15 to 17, and high fixed contact 20
and the common fixed contact 22 are electrically connected. While the switch lever 5 is being rotated from the low position to the high position, the auxiliary movable contact 16 is always in contact with the auxiliary fixed contact 21, and therefore the low fixed contact 18 is always electrically connected to the common fixed contact 22 during this period. Therefore, even if the conduction between the switching movable contact 15 and each of the fixed switching contacts 18 to 20 is unstable, the fan motor 40 is driven in a low state, and the operation is stabilized. Furthermore, arc generation during switching of the switching movable contact 15 is reduced. When the switch lever 5 is moved to the OFF position, all of the movable contacts 15 to 17 are located on the common fixed contact 22.

each movable contact 15 when rotated to the off position.
Since all of the movable contacts 15 to 17 are located on the common fixed contact 22, it is less likely that an insulating material will be attached to the contact surfaces of the movable contacts 15 to 17, resulting in high contact reliability.
The switch lever 5 is supported by the lever support protrusion 13 (Fig. 2) protruding from the cover 2 while being pressed by the contact spring 9.
This prevents wobbling and stabilizes contact pressure. Moreover, since each terminal 18 etc. is held down by the portion 2b (FIG. 8) of the cover 2, rattling of the terminal 18a etc. can be prevented and reinforced. Since the cross-sectional shape of the movable switching contact 15 is trapezoidal and the tip is a flat surface, there is little change in contact pressure when passing through the gap B between the fixed switching contacts 18 to 20 as shown in FIG. Therefore, arcing is reduced and contact life is extended. Furthermore, chattering is also prevented. The common movable contact 17 and the auxiliary movable contact 16 have an arcuate cross-sectional shape so that there is no problem when switching, and therefore there is little insulating material involved. Since the tip of each terminal 18 etc. is in the shape of a plug-in connector, lead wire connection can be made with one touch using a connector or the like. The contact holder 7 can be attached with one touch. That is, Fig. 7A
As shown in FIG. 7B, by simply inserting the moderation ball holding frame 7b into the forked plate-shaped portion 5a of the switch lever 5 and pushing down the groove-shaped portion 7a in the direction of the arrow, the front and rear locking claws 35 are removed as shown in FIG. 7B. , 36 engage with the switch lever 5, and the contact holder 7 is fixed to the switch lever 5. Moreover, there is no need for fixing parts such as screws, so the number of parts can be reduced. As shown in Fig. 8, an external force is applied in the direction of the arrow, and the switch lever 5 moves the contact holder 7.
Even if a force is applied to remove it, the moderation ball holding frame 7b cannot bend inward because the steel moderation ball 10 is inside, as shown in FIG. The claw 35 never comes off. Case 1
Since the side wall of the switch lever 5 is used as a stopper as shown in FIG. 9, it is strong against abnormal operating force from the outside.
