PROBLEM TO BE SOLVED: To improve the operation touch and durability of a neutral-point return type rotary switch.SOLUTION: The rotary switch includes a case 21 which has a switch contact 30 formed on an inner bottom surface 21c, a rotary operation member 26 which is incorporated rotatably in the case 21, and has a slider 27, coming into slide contact with the switch contact 30, fitted to a lower surface, an elastic member 25 which is incorporated in the case 21, and a cover 28 which covers an upper surface of the case 21 to restrict an upward movement of the rotary operation member 26. The elastic member 25 has elasticity for returning the rotary operation member 26 to a neutral point and also has elasticity for energizing the rotary operation member 26 upward. |
