Abstract: In a switch, the speed at which contacts are separated from each other is increased without depending on the speed at which an operating member is operated, so that an arc is prevented from being generated, to prevent the operating member to be deformed by heat generation and prevent the durability of the switch to be decreased due to the abrasion of the contacts.

The leaf spring has a portion projecting in a U shape. The U-shaped portion is engaged with the center of the movable contact member. When the slider is moved, the U-shaped portion is distorted in the transverse direction. When the slider is further moved, the U-shaped portion gets beyond the fulcrum, so that the movable contact is rapidly separated from a normally open fixed contact.
