  • a holding hole 254 is formed in the central portion of the bottom surface of the knob 250.
  • the knob 250 holds the upper portion 212A of the pressing member 212 by fitting the upper portion 212A of the pressing member 212 into the holding hole 254.
  • the pressing member 212 when the knob 250 is pressed by the operator, the pressing member 212 whose upper portion 212A is held by the knob 250 elastically deforms the support portion 232 and the outer peripheral portion 234 of the cover member 230. Moves downward with the knob 250. As a result, the pressing member 212 presses the top of the movable portion 144A of the switch 144 provided inside the case 210 by the pressing surface 212D which is the bottom surface thereof. As a result, the switch 144 is switched to the on state. As a result, the two lead wires 146 are in a state of being electrically connected to each other.
  • the knob 250 and the pressing member 212 are both formed by using a hard material, and no elastic member is interposed between the knob 250 and the pressing member 212. Therefore, the switch device 200 of the present modification can press the switch 144 by the pressing member 212 with almost no attenuation of the operating load applied to the knob 250. Therefore, according to the switch device 200 of the present modification, a more direct operation feeling can be obtained.
  • the switch device 200 of this modified example may not be provided with the knob 250 and the pair of hooks 252. That is, the operator may directly press the upper portion 212A of the pressing member 212.
  • another knob formed by using a hard material or an elastic material may be fixedly provided on the upper portion 212A of the pressing member 212.
