When the force is no longer applied to the handle 2, the push button handle 11 moves out of the body 10. At this time, the handle 2 pushed by the push button handle 11 rotates in a direction away from the front surface of the switch body 1, and stops at a position where the claws 201 of the pair of retaining pieces 200 are caught on the periphery of the insertion hole 103.

  Further, the display body 22 is provided so as to be movable with respect to the base member 20, and is configured to be moved by a driving piece 13 that is movably operated from the switch body 1 in accordance with a pressing operation of the push button handle 11. . Specifically, in accordance with the state of the contact portion, the front end portion of the drive piece 13 protrudes from the entrance / exit hole 102 on the front surface of the container body 10 so as to freely advance and retract, and the display body at the front end portion of the drive piece 13 protruding from the entrance / exit hole 102 22 is driven, and the display body 22 moves in the recess 203 of the handle 2. As a result, the characters (“ON” and “OFF”) of the label 25 attached to the surface of the display body 22 can be alternatively viewed from the front of the handle 2 through the display window 202 (see FIG. 4). .

  Here, as shown in FIG. 1, the decorative member 21 has a facing portion 211 that faces the display window 202 of the base member 20 and a non-facing portion 212 that does not face the display window 202. The diffusion layer 210 is provided on the surface of the non-facing portion, but the diffusion layer 210 is not provided on the surface of the facing portion.

  That is, when the diffusion layer 210 is provided on the surface of the facing portion, it is difficult to visually recognize the characters on the label 25 attached to the surface of the display body 22 from the front of the handle 2. Therefore, in the handle 2 of the present embodiment, since the diffusion layer 210 is not provided on the surface of the facing portion 211 of the decorative member 21, the characters on the label 25 can be easily seen from the front of the handle 2 through the display window 202. (See FIG. 4).

  As described above, the handle 2 of the present embodiment is a handle that is rotatably attached to the front surface of the switch body 1 and that is used to push the push button handle 11 of the switch body 1, and includes a base member 20, a decorative member 21, and the like.
