The engagement cam body 38 on the left side of the slide cam 33 is located on the left side of the engagement protrusion 34 on the left side of the reversing handle 31, and the slide cam 33 is pushed to the left as the reversal handle 31 rotates. As shown in FIG. 12, the slide cam 33 slides to the left in the figure. Thus, as shown in FIG. 13, the reversing handle 31 is tilted to the left in the drawing, the reversing spring 30 is reversed, the switch 24 is reversed, and the movable contact 29 is separated from the fixed contact 25, that is, the contact 100 is Invert to open state. Thereafter, when the pressing force applied to the piano handle 43 is released, the push button handle 32 is pushed back by the spring force of the return spring 37 as shown in FIG. 14, and the piano handle 43 in contact with the push button handle 32 is also returned to the original position. Return. At the same time, the slide cam 33 also slides by the spring force of the spring piece 33a and returns to the center position.

Thus, when the pressing force is applied again to the piano handle 43 while the contact point 100 is open, the reversing handle 31 can be rotated in the same manner as the above-described operation. However, when the contact point 100 is open, the engaging projection 34 on the right side of the reversing handle 31 comes into contact with the engaging cam body 38 on the right side of the slide cam 33.
The movable contact 29 is brought into contact with the fixed contact 25 via. If the pressing force is released from the piano handle 43 after the contacts 100 are inverted in this manner, the state returns to the state shown in FIG. In short, in this embodiment, the contact 100 is opened and closed each time the piano handle 43 is pressed. That is, the engagement protrusion 3 between the slide cam 33 and the reversing handle 31
The conversion mechanism that converts the pressing operation of the push button handle 32 into the swing of the reversing handle 31 is constituted by the 4 and the return spring 37.

By the way, the above-mentioned mounting frame 2 is capable of mounting three switch bodies 1 each having a module size, and is therefore referred to as a mounting frame 2 for three. That is, the side pieces on both sides of the window hole 2a of the mounting frame 2 include:
The mounting claws 11a, 11b of the switch body 1 are locked.
One set of appliance mounting holes 2b, 2b is provided for each three sets,
Three mounting positions of the switch body 1 can be selected in the window hole 2a. Here, the longitudinal direction of the window hole 2a is made to coincide with the lateral direction of the switch body 1 so that the switch body 1
Are attached to the attachment frame 2, the three attachment positions will be referred to as an upper end position, a center position, and a lower end position, respectively.
A switch body 1 having a module size is mounted on the mounting frame 2.
15 is a piano handle 43 used when one is attached, and as shown in FIG. 15, opening windows 120a, 130a of plates (plate frame 120 and decorative plate 130).
The piano handle 43 having such a size that it can be covered by one piece is referred to as a piano handle 43 for one piece. Similarly, a piano handle 43 used when two switch bodies 1 each having a module size are mounted on the three mounting frames 2.
33, the opening windows 120a and 130a of the plate attached to each switch main body 1 as shown in FIG.

Is fixed to the back side of the piano handle 43, so that the name cover 253 is attached to the front surface of the piano handle 43 and the door 254 is attached to the back surface of the piano handle 43. The assembly work for assembling the name cover 253 and the door 254 can be extremely simplified.

At the other end on the surface of the piano handle 43, a push position indicating protrusion 114 is provided at the center in the vertical direction.
This indicates that the end to which the pressing force is applied to the piano handle 43 is on the pressing position indicating protrusion 114 side. A plurality of decorative lines 115 are formed in stripes on the upper and lower sides of the name cover 253 on the surface of the piano handle 43, respectively. The makeup line 115 irradiates the synthetic resin molded product forming the piano handle 43 with a laser beam to a carbonization reaction so that the surface of the piano handle 43 is not substantially formed with irregularities (there is no rough feeling when touched by hand). It is formed by causing a color difference so as to generate a color difference with other portions. In short, the makeup line 115 and the name cover 253 are formed independently. Therefore, the name card 250
In a type that does not particularly require the name cover 253, as shown in FIGS.
One piano handle 43 without the name cover 253 and the door 254 may be employed.

The piano handle 2 is mounted such that the vertical center position of the piano handle 1 coincides with the vertical center position of each piano handle 2. As a result, the same two piano handles 43 can be used in common without distinguishing between the upper and lower positions. The two piano handles 43 have different vertical dimensions from the one piano handle 43, but the other components including the name cover 253 are the same.
Is the same as Therefore, since the makeup line 115 and the name cover 253 are independent, the name card 25
0 and the name cover 253 are not particularly required, as shown in FIG. 44 and FIG.
Alternatively, two piano handles 43 without the name cover 253 and the door 254 may be employed.

When three switch bodies 1 are mounted in the window 2a of the mounting frame 2, as shown in FIGS. 46 to 52, the switch bodies 1 are mounted at the upper end position, the center position, and the lower end position, respectively. FIG. 5 shows each switch body 1.
