Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION FIELD The present invention is mainly used for operation of a switchboard, an operation panel, and the like, and relates to a select pushbutton switch having a select switch function and a pushbutton switch function.

2. Description of the Related Art Conventionally, a select push-button switch having a select switch function and a push-button switch function performs an open / close operation by rotating a select knob and an open / close operation by a push operation of a push button. It was difficult to confirm the operation state of the push button when the push button moved up and down with the rotation.

Problems to be solved by the invention When the select knob of the select push button switch is turned, the operation push button moves up and down due to the projection inside the holder and the cam groove of the operation rod. Since there is no means for performing the operation, it takes a long time to check the setting position of the select knob and the operation state of the push button, and there is a problem that the operation is difficult.

Means for Solving the Invention The present invention is proposed in view of the above-mentioned contents. The protrusion provided on the operation rod is engaged with the inner cam of the two-stage cam, and the rotation of the guide ring causes the operation rod to move up and down. In addition, the operation state of the operation rod can be surely confirmed by the mark provided on the guide ring.

Action of the invention The vertical movement of the operation rod due to the rotation of the guide ring can be easily confirmed by the mark provided on the guide ring, and the operation of the select switch and the push button switch becomes easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, reference numeral 1 is a case having a through hole 2 at the center, 3 is a bottom cover fixed to the bottom of the case 1, 4 is an operating rod, a push button 5 is fixed at the top, and 6 is a guide. The operating rod 4 penetrates into the hollow by the ring, moves up and down, and is inserted into the through hole 2 of the case 1 to be rotatable. Numeral 7 denotes a hollow holder, the upper part of which is fixed to the guide ring 6, and numeral 8 denotes a hollow two-step cam having a chevron cam 9 at the lower part. The operation rod 4 is inserted into the hollow of the step cam 8. Reference numeral 11 denotes a ring which is rotatably fixed to the lower end of the holder 7, and reference numeral 12 denotes a fastening ring which is screwed to the screw portion 13 of the case 1 and fixed to the panel. 14 is a click cam which is installed in case 1 and has a spring 15
A click feeling is given when the two-stage cam 8 rotates, and a switch unit 16 opens and closes the contact base 17 by pressing the operating rod 4 and rotating the two-stage cam 8 to open and close the contact base 17. Protrudes from the hole 22 of the bottom cover 3, and 18 is fixed to the upper end of the guide ring 6 by a mark. Marks 19a and 19b are provided on the inner surface of the mark 18 as shown in FIG. Can be checked. The projection 20 is formed integrally with the operation rod 4, and the projection 20 is engaged with the inner cam 10 of the two-stage cam 8, and the projection 20 is guided by the inner cam 10 with the rotation of the guide ring 6. 4 moves up and down. A return spring 21 constantly urges the operation rod 4 upward. As shown in FIG. 3, the inner cam 10 is
The projection 20 is locked at the ascending position a, and is locked at the descending position b at every 90 °, so that the operation rod 4 moves up and down with the rotation of the guide ring 6.

Next, the operation will be described. In the opening / closing operation by the pressing operation of the operating rod 4, when the push button 5 is pressed, the contact base 17 of the switch unit 16 is pressed by the lower surface of the ring 11 to open and close the contacts. When the guide ring 6 is rotated, the two-stage cam 8 rotates and the chevron cam 9 presses the contact base 17 to open and close, and the ring 11 rotates simultaneously with the rotation of the guide ring 5. Contact base 17 when pressed
Can be pressed, and the projection 20 of the operating rod 4 is the inner cam of the two-stage cam 8.
The operation rod 4 is moved up and down by being guided by the switch 10, and the switch unit 16 is moved.
The contact base 17 can be held in two positions, an OFF state and a neutral state.
Can be visually confirmed with the marks 19a and 19b.

Effect of the Invention As described above, in the present invention, the operation rod moves up and down with the rotation of the guide ring by the action of the projection provided on the operation rod and the inner cam of the two-stage cam, and is operated by the mark of the mark fixed to the guide ring. Since the operating state of the rod can be checked at a glance, there is an effect that the rotating operation of the guide ring and the pressing operation of the push button can be quickly and reliably performed.
