ムの回転角度とに誤差が生じることになる。(Problems to be solved by the invention) In the conventional switch as described above, the rotor and rotating cam are separate parts that are assembled by fitting, so manufacturing variations in each part occur. As a result, the fitting part between the rotor and the rotating cam may be hard or loose, and if the fitting is tight, it will be difficult to assemble the rotor and the rotating cam, and the rotating cam will be deformed. If there is any slack, an error will occur between the rotation angle of the rotor and the rotation angle of the rotating cam by the amount of slack.

れにも限度があつた。 In both of these situations, an error occurs in the rotational movement of the rotary cam relative to the rotational movement of the rotor when the drawstring is pulled, which results in an error in the movement of the movable contact piece, causing product variations in the on/off state of the switch. Therefore, the product becomes expensive due to the large number of parts and assembly man-hours, and a decrease in yield. As a means to solve these problems, there are methods such as improving the precision of molds and improving the precision of molding conditions, but these methods also have limitations.

る。 First, in the switch-off state, the cam protrusion 21 of the rotating body 12 presses the movable contact piece 37 to separate it from the fixed contact piece 35. In this state, the rotating body 12 is urged in a direction opposite to the switch operating direction S by the reaction force of the movable contact piece 37 via the cam protrusion 21, but the tip of the rotation regulating piece 39
Reverse rotation is restricted by contacting the stop cam 23 of the reverse rotation regulating portion 22 of No. 2. Further, the lever 25 is located on the rotation receiving cam 18 at a position where the string attachment piece 28 comes into contact with the rib 7 due to the bias of the spring 31.

12は約45°回転している。 Then, when the drawstring 29 is pulled, the lever piece 27 of the lever 25 moves in the switch operation direction S, slides on the rotation receiving cam 18 that is currently in contact, and engages with the previous rotation receiving cam 18. , the rotating body 12 is rotated in the switch operating direction S by pressing the rotation receiving cam 18 in front of it. As the rotating body 12 rotates, the cam protrusion 21 comes off the movable contact piece 37 and releases the pressure, and the movable contact piece 37 contacts the fixed contact piece 35 and is electrically connected to the switch-on state. . Also, due to the rotation of the rotating body 12, the next stop cam 23 passes over the tip of the rotation regulating piece 39,
Furthermore, when the lever piece 27 faces the pull-out hole 41,
When the drawstring 29 is pulled out from the switch body 1 to its maximum extent, the drawer stops, and at this point the rotating body 12 has rotated approximately 45 degrees.

ツプカム23に当接して規制する。 After that, when the drawstring 29 is released, the lever piece 27 rotates in the opposite direction to the switch operating direction S due to the action of the spring 31, and the rotation receiving cam 1 currently mounted
8 and rests on the next rotation receiving cam 18, and returns to the predetermined position where it comes into contact with the rib 7. This lever piece 2
7 returns, the rotating body 12 moves in the switch operating direction S.
However, the rotation regulating piece 39 comes into contact with the stop cam 23 to regulate it.

The rotating body 12 is rotated by approximately 5° in the switch operating direction S by the lever piece 27 of 5, and the rotation of the rotating body 12 causes the cam protrusion 21 to press the movable contact piece 37 and release the movable contact piece 37 from the fixed contact piece 35. The switch is turned off.

い。 As mentioned above, by pulling the drawstring 29,
The lever 25 rotates the rotating body 12 consisting of the rotor 13 and the rotating cam 14 by approximately 45 degrees, and the movable contact piece 37 is brought into contact with the fixed contact piece 35 by pressing and releasing the pressure by the cam protrusion 21, thereby turning the switch on and off. Perform switching. At the time of this switching, the rotation of the rotor 13 transmitted through the lever 25 by pulling the drawstring 29 is transmitted to the integrated rotating cam 14, and the cam protrusion 21 of this rotating cam 14 opens and closes the movable contact piece 37. Therefore, there is no error in rotation transmission, and there is little variation in switch operation from product to product.

According to the present invention, since the rotor and the rotating cam are integrally formed, the rotation received by the rotor by the lever can be transmitted to the rotating cam without causing any error.
Moreover, the axial movement of the rotor can be restricted by the rotation restriction piece that engages with the reverse rotation restriction section between the rotor and the rotating cam, reducing the variation in switch operation for each product and ensuring accurate switch operation. By improving the product yield and reducing the number of parts and assembly man-hours, the product can be made cheaper.
