And, because the lower surface of the reinforcement 41 on key top 36 and the upper surface of elasticity movable body 17 all are plane, then under laying state, can on elasticity movable body 17, apply power useless, and improve the durability of elasticity movable body 17.

And, because whole current-carrying part 31a of elasticity

movable body

17,31b, 31c, 31d are surrounded by the periphery wall 32 of a below thin thickness, then these current-carrying

parts

31a, 31b, 31c, 31d can be by pollutions such as dust, and can realize the miniaturization of elasticity movable body 17.

On wiring board 10, by current-carrying

part

22,23,24,25, the periphery wall 27 of the below thin thickness of 31 periphery, 28,29,30,32 spaces that surrounded are interconnected by being communicated with ditch 43, simultaneously, be connected with the outside by being communicated with ditch 44, therefore, at control switch device 1, sleep push-button switch 2, mode push-button switch 3, A push-button switch 4, in the operation of B push-button switch 5, even these spaces dwindle, air in these spaces can flow freely, and keep the internal pressure in these spaces constant, then the control switch device 1, sleep push-button switch 2, mode push-button switch 3, A push-button switch 4, the action of B push-button switch 5 is carried out smoothly.

And for example, when between the ledge 37a, the 37b that press key top 36, key top 36 tilts to this direction, and

electrical contact

11a, 11b become on-state simultaneously.

Because the retainer 34 as supporting point part is rigid plastics systems, then has the hardness of appropriateness and the lubrification of itself, and be cheap.Also can make retainer 34, like this, retainer 34 is slided with respect to wiring board 10, and can improve resistance to wear with metal.
