A transparent portion 76b is formed at a portion corresponding to a part of the display window 76a at the center of the display window 76a, and the characters of the display sheet 72 are passed through the display window 76a and the transparent portion 76b of the display cover 76 to the front side of the piano handle 43. It can be visually recognized from. That is, at one of the two positions, the notation 72a of “off” becomes visible from the transparent portion 76b, and at the other position, the notation 72a of “on” becomes visible from the transparent portion 76b. In addition, as in the case of the first embodiment and the third embodiment, a display window 76a is provided at the center of the display cover 76 in the case where a position indicator light or an on-confirmation light is provided in the switch body 1. A light transmitting portion 76c is formed at a portion corresponding to the portion and adjacent to the transparent portion 76b. A lens 113 ′ having the same function as the lens 113 shown in the first embodiment or the third embodiment is attached to the back surface of the piano handle 43. 76c. Lens 1
13 'is extended in the up-down direction with respect to the translucent part 76c.

By the way, a holding plate 77 is fixed to the piano handle 43 to hold the display body 70 with the back surface. That is, the display body 70 is held in a space formed between the back surface of the piano handle 43 and the pressing plate 77,
The display 70 is prevented from falling off the piano handle 43. A notch window 77a is formed in the center of the holding plate 77, and the above-described three on-off projections 70b are movable in the notch window 77a. Also, the holding plate 77
The notch groove 7 into which the central part of the lens 113 'is fitted

A part (not shown) is provided, which is based on this. Therefore, the display body 70 is urged by the spring force of the return spring 78 toward one of the two positions, which is the movement range. The inclined surface 70c of the on / off projection 70b moves the display body 70 to the other of the two positions against the spring force of the return spring 78 when a forward force acts on the inclined surface 70c. It is inclined to let.

The switch body 1 used in this embodiment is provided with the on / off driving piece 71 integrally with the reversing handle 31 as described above, and the front end of the on / off driving piece 71 is movable on the front wall of the cover 5a. An access hole 74 to be inserted is formed.
The on / off drive piece 71 protrudes from the swinging direction of the reversing handle 31 on the side closer to the shaft portion 192. When the contact point 100 is open, the tip of the on / off drive piece 71 retreats into the access hole 74. , When the contact 100 is closed, the on / off driving piece 71
Is projected from the access hole 74.

Next, the operation of moving the display 70 with the swing of the reversing handle 31 will be described with reference to FIGS. 67 and 68.
This will be described with reference to FIG. The figure shows a state in which three switch bodies 1 are mounted on the mounting frame 2. As can be seen from the figure, at the center position of the mounting frame 2, the central on / off projection 70 b of the three on / off projections 70 b is shown. The on-off drive piece 71 corresponds to
At the upper end position (the right end position in the figure), the on / off drive piece 71 corresponds to the on / off protrusion 70b at the lower end (the left end in the figure), and at the lower end position, the on / off drive piece 71 corresponds to the on / off protrusion 70b at the upper end. FIG.
Reference numeral 7 denotes a state in which the contacts 100 of all the switch bodies 1 are open, and the transparent portions 76 of the respective piano switches 43.
b shows a state where the notation 72a of "OFF" of the display sheet 72 corresponds to each. FIG. 68 shows a state in which the contacts 100 of all the switch bodies 1 are closed, and a state in which the notation 72a of the display sheet 72 corresponds to the transparent portion 76b of each piano switch 43. Is shown. In the figure, the range of the transparent portion 76b is D, and the notation of
The range of a is denoted by N1, and the range of the notation 72a of "OFF" is denoted by N2. That is, when the range of N1 overlaps with the range of D, it means that the notation 72a of "ON" can be visually recognized from the transparent portion 76b.

At the position shown in FIG. 67 where the contact point 100 is open, the leading end of the on / off driving piece 71 is retracted to such a degree that it hardly projects from the access hole 74. Also, the on / off driving piece 7
1 has an inclined surface 70c near the tip of the on / off projection 70b.
In this state, the display body 70 is
Due to the spring force of No. 8, it is located at the lower position (left position in the figure) of the above two positions, and the transparent portion 76b corresponds to the notation 72a of "OFF". Here, piano handle 4
When the reversing handle 31 is reversed by pushing the button 3, the tip of the on / off driving piece 71 provided integrally with the reversing handle 31 projects from the access hole 74 and the inclined surface 70c of the on / off projection 70b.

Here, the depth of the lock recess 70e is such that the tip of the on / off driving piece 71 is inserted into the lock recess 70e even when the pressing force on the piano handle 43 is removed and the piano handle 43 returns to the original position. The display 70 is not moved even if the pressing force on the piano handle 43 is removed.

When the inversion handle 31 is inverted by pushing the piano handle 43 from the state where the notation 72a of “in” corresponds to the transparent portion 76b, the tip of the on / off drive piece 71 retreats into the access hole 74, The locked state of the display 70 is released. Therefore, the display body 70 returns to the original position (that is, the position in FIG. 67) by the spring force of the return spring 78, and the notation 72a of "OFF" corresponds to the transparent portion 76b. At this time, the contact 100 is open.
