<p>PURPOSE:To obtain a switch device which can be easily assembled and is free of malfunction during operation. CONSTITUTION:Bosses 3a and 3b and a flat plate shaped supporting point 7 are formed in a control knob 2. Hinges 4a and 4b are formed between the control knob 2 and a frame 5. A groove-shaped supporting point receiver 24 having a roughly V-shaped section is formed on the top of a guide 22. Switches 34a and 34b are mounted on a board 33. The claw 6 of an operating part 1 and the claw 25 of a guide part 21 are fitted through board pores 34a and 34b and mounted on the board 33. The tip ends of the bosses 3a and 3b are located opposite the top parts 35a and 35b of the switches 34a and 34b of the board 33 at their specified intervals, when for example, an operating display 2a side is pressed, the control knob makes 2 rotational motion around the center of the supporting point 7 and the contact part of the supporting point receiver 24, the top part 35a is pressed at the boss 3a, and the switch 34a is set in its ON position. The hinge 4a is bent and the hinge 4b is extended. When pressing on the operation display part 2a side is stopped, the switch is returned to its original position by means of the restoration force of the hinges 4a and 4b.</p> |
