PURPOSE: To provide a snap action type operation feel at low cost by pressing an overhanging and bent movable member by a pushbutton to be deformed by resiliency, and providing a step for guiding a movable contact at a forward end of the movable member from a fixed contact A to B to drop.
CONSTITUTION: A movable member 6 comprising a spring plate material is supported in a case 1 in an overhanging condition, and a movable contact 6b is constantly in contact with a fixed contact 3a in a restoration attitude where a pushbutton 5 is pushed up. As the button 5 is pushed down, the whole body of the movable member 6 is deformed resiliently about the center of a base part. so a bent part 6a is deformed to be elongated in a -form, and the contact 6b slides along a contact guide surface (s) to be displaced. The contact 6b thus gets off the contact 3a to drop into a guide step (d), where operation force of the button 5 is changed from a linear increase into quick decrease to get it in contact with a fixed contact 4a. After this, as the contact 6b is in contact with the contact 4a, it slides to be displaced, and the operation force of the button 5 is increased again. Switch-on action can thus be recognized as an operation feel in simple structure and at low cost.
