付与するようになっている。A reversing handle 31 is rotatably attached to the case 5b at a substantially central portion in the longitudinal direction and one side end portion in the lateral direction, and the reversing spring 1 is formed of a coil spring.
The cylindrical portion 3 of the cylindrical inversion handle 31 in which 01 is opened downward
1a, and the lower end of the reversing spring 101 is opened / closed.
Locking protrusion 2 at a position above the portion where the movable contact 29 of FIG.
It is locked to 4a. The reversing handle 31 is rotatably attached by pivoting the inverted triangular shafts 31b provided on both sides to a bearing (not shown) formed on the inner wall of the cover 5b. Therefore, the movable contact 2 of the opening / closing body 24
9, the spring force of the reversing spring 101 acts on the locking protrusion 24a above the opening 9, and the reversing spring 101 causes the opening / closing body 24 to move.
Contact pressure can be applied without loss (that is, when the position of the movable contact 29 is laterally displaced from the locking projection 24a, which is the operating portion of the reversing spring 101, the movable contact 29 is reversed as in the present invention. (There are variations and loss of contact pressure as compared with those directly above the locking projection 24a, which is the operating portion of the spring 101). The reversing spring 101 holds the reversing posture, and the movable contact 29 is fixed to the fixed contact 25a.
Alternatively, it is held in contact with 25b with a predetermined contact pressure. That is, in the state where the opening / closing body 24 is rotated rightward as shown in FIG. 1 and the movable contact 29 is in contact with the fixed contact 25b, a spring force is applied in a direction in which the movable contact 29 makes elastic contact with the fixed contact 25b. In the state where the opening / closing body 24 is rotated to the left as shown in FIG. 2 and the movable contact 29 is in contact with the fixed contact 25a, the movable contact 29 exerts a spring force in a direction of elastically contacting the fixed contact 25a. ing.

3 shows a state in which the pressing operation end of the piano handle 43 is fully pushed, and FIG. 12 shows an operating state in the middle thereof,
14 shows a state in which the pressing operation of the piano handle 43 has been released and the piano handle 43 has returned, FIG. 16 shows a state in which the pressing operation end of the piano handle 43 has been pressed fully again, and FIG. 15 shows FIG. 16 shows an operation state in the middle of 16 and FIG. 11 shows a state in which the pressing operation of the piano handle 43 is released and the piano handle 43 is returned in the state of FIG. Now, assuming that the piano handle 43 is operated in the state shown in FIG. 11, the push button 100 is pushed by the operation of the piano handle 43 as shown in FIG.
09 is pushed down, and the lower end of the push button 100 pushes the first pressed portion 104 facing the lower end of the push button 100. When the first pressed portion 104 is pushed, the opening / closing body 2
4 moves from the state of FIG. 12 to the state of FIG. 13, and the movable contact 29 makes elastic contact with the fixed contact 25a. And
In this case, when the opening / closing body 24 passes through the vertical state as shown in FIG. 12, the spring force of the reversing spring 101 to the opening / closing body 24 is reversed, and the movable contact 29 comes into contact with the fixed contact 25a as shown in FIG. In the state, it acts as a spring force for elastically contacting the movable contact 29 with the fixed contact 25a so as to maintain the contact. After this reversal, when the pushing down force of the piano handle 43 is released, as shown in FIG.
The push button 100 is pushed up by the spring force of 09, and the piano handle 43 returns to the original state at this time. After that, when the piano handle 43 is operated again as shown in FIG. 15, the opening / closing body 24 reversely rotates in the opposite direction to the above case as shown in FIG. 16, whereby the movable contact 29 is fixed. Contact switching is performed so as to come into contact with the contact 25b, and when the piano handle 43 is pushed down and the force is released, the contact is again returned to FIG.
It returns to the state of 1. And the piano handle 4
In order to switch the contacts by operating 3 to invert the opening / closing body 24, in the present invention, the piano handle 43 → push button 100
→ The opening / closing body 24 is formed by three-stage transmission means, and the operation stroke of the piano handle is shorter than that of the conventional five-stage transmission means. Also, by shortening the distance between the first pressed portion 104 and the second pressed portion 105 of the overhanging portion 102, the operation stroke can be further shortened.

Since a push button switch is configured with and a piano handle that pushes the push button by a piano touch operation is attached to the push button switch, the operation of the piano handle can be controlled by three-stage transmission means such as piano handle → push button → open / close body. It can be converted into a reversing operation, and the operation stroke of the piano handle can be shortened to improve the operation feeling as compared with the conventional five-stage transmission means. At the substantially center of the cover, the outside of the cover is projected, and the lower end is pivotally supported at one end of the opening / closing body. Positioned below the button, the first pressed portion facing the lower end of the unpressed push button by the piano handle is placed on one side of this overhanging portion while the opening / closing body is in contact with the contact on the other side. By providing the second pressed portion facing the lower end of the push button that is not pressed by the piano handle while the opening / closing body is in contact with the contact on one side on the other side of the overhanging portion, the piano handle is provided. The pressing force is applied to the push button in the substantially central portion of the cover, and the push button operates the first and second pressed portions of the projecting portion of the opening / closing body immediately below the push button. As a result, the operation of the piano handle is performed. There is an advantage that the force can be smoothly converted into the rotative power of the opening / closing body and the operation of the push button switch is stabilized, and in this case, the first pressed portion and the second pressed portion of the protruding portion are By shortening the distance between the And a Kudekiru things, also, by urging the reversing spring to the opening and closing member at the upper position of the portion provided with the movable contact, is capable of giving the contact pressure of the closing member without loss.
