<p>PROBLEM TO BE SOLVED: To share parts and to simplify operation by reversing a contact part opening/ closing body in a switch body mounted on a specific number of tool mounting means disposed along the longitudinal side of a window hole of a mount frame with a reversal means, and by abutting and returning a piano handle covering the opening in a decorative frame facing opposite the window hole from the head of a push-button handle. SOLUTION: A mount frame has a window hole provided with three tool mounting means in common specifications. The dimension in the short direction is about one-third of that in the longitudinal direction of the window hole. A push-button switch 5 is mounted on the window hole. The push-button switch 5 is constituted of a body 5a and a cover 5b. Connecting terminal housing 13 and 14 within the body 5a accommodate a connecting terminal and a first and second connecting terminals, and a central housing 23 accommodates fixed terminal 25 a and 25b and an open/close body 24. A moving contact 29 on both sides of the top of the open/close body 24 that is driven by a reversal mechanism, including a push-button handle 32, etc., contacts/separates from the fixed terminals 25a and 25b. The pressure of a piano handle 43 annexed to the push-button switch 5 drives the push-button handle 32 to be operated in the manner of piano touch.</p> |
