<p>PROBLEM TO BE SOLVED: To provide a switch, the safety of which is enhanced by working on a position in the vicinity of the movable contact of the switch, at the time of trigger operation, thereby preventing occurrence of bouncing and enhancing the durability of the contact, and allowing a welded contact to be separated forcibly.SOLUTION: A trigger switch includes a movable contact piece 15 having a first movable contact at one end and a second movable contact 24 at the other end, and rotating while being supported by a support member, a rotary member for sliding while pressing the slide surface of the movable contact piece and rotating the movable contact piece like a seesaw, a first terminal having a fixed contact, a second terminal 28 having a second fixed contact 27, and a protrusion 31 for preventing the bouncing formed to extend from the sliding body in the sliding surface direction of the movable contact piece. When the rotary member slides on the sliding surface of the movable contact piece, and the second movable contact is brought into open state, the protrusion for preventing the bouncing abuts against the sliding surface 34 of the movable contact piece, and suppresses vertical movement thereof.</p> |
