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.

対して強じんである。 Although it operates in this way, the following advantages can be obtained because of the above-described configuration. switch lever 5
each movable contact 15 when rotated to the off position.
Since the movable contacts 15 to 17 are all located on the common fixed contact 22, it is less likely that an insulating material will adhere to the contact surfaces of the movable contacts 15 to 17, and the reliability of contact will be high.
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. In addition, since each terminal 18a and the like are held down by the portion 2b of the cover 2 (FIG. 8), rattling of the terminal 18a and the like 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, when passing through the gap B between the fixed switching contacts 18 to 20 as shown in FIG.
There is little change in contact pressure, which means less arcing and longer contact life. 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, as shown in FIG. 7A, 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, as shown in FIG. 7B. The front and rear locking gourds 35 and 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. Even if an external force is applied in the direction of the arrow as shown in FIG. 8, and a force is applied by the switch lever 5 to remove the contact holder 7, the moderation ball holding frame 7b will not hold the steel moderation ball 10 as shown in FIG. Since it is inside, it cannot bend inward, and therefore the locking melon 35 will not come off. Since the side wall of the case 1 is used as a stopper for the switch lever 5 as shown in FIG. 9, it is strong against abnormal operating forces from the outside.
なお、前記実施例ではハイ、ミドル、ローの３

２段切替えとしてもよく、また切替固定接点を増
やして４段以上の切替えとしてもよい。 In addition, in the above embodiment, there are three types: high, middle, and low.
Although the switching is performed in stages, the high fixed contact 20 may be omitted to perform two-stage switching, or the number of fixed switching contacts may be increased to provide four or more stages of switching.

アークの発生が少なくなるという効果がある。[Effects of the invention] In the switch, when the switch lever is rotated to the OFF position, all movable contacts are located on the common fixed contact, so it is less likely that insulators will adhere to the contact surfaces of the movable contacts. Contact becomes more reliable. Further, the switch lever is provided with an auxiliary movable contact, and an auxiliary fixed contact is provided in which the auxiliary movable contact continuously contacts each of the fixed switching contacts over an angular range in which the switching movable contact contacts each switching fixed contact. Therefore, while switching the switch lever to each switching fixed contact,
The auxiliary movable contact always contacts the auxiliary fixed contact 21. Therefore, by connecting the auxiliary fixed contact to the terminal for the minimum rotation of the load, even if the contact of each switching fixed contact is unstable, the load can be maintained at the minimum rotation speed by contact with the auxiliary fixed contact. As a result, the operation becomes stable. Moreover, there is an effect that the occurrence of arcing when switching the contacts is reduced.
