PROBLEM TO BE SOLVED: To provide a lever switch which can surely and accurately return to an initial state when recovering from a tilted state.SOLUTION: A tilt switch is disclosed which is formed from: a case including a plurality of fixed contact points; a lever including a rotary part 22 which includes a contact piece and on which an opening is formed, and an operation part 21 protruding from the case; and a cover accommodating the lever in the case. In the opening, energizing means 30 is disposed. An inner side face of the opening is formed from an active-side inner side face 26 on which pressure from the energizing means acts, and a guide inner side face 29 excluding the active-side inner side face. The active-side inner side face is formed while being spread in a lateral direction from a top end portion 28 where the pressure from the energizing means is minimized. By applying pressure from the outside to the operation part, the lever is tilted while gradually greatly receiving the pressure from the energizing means to the active-side inner side face, and the contact piece is brought into contact with the plurality of fixed contact points at a fixed tilting angle, so that a circuit is switched. |
