PURPOSE:To make conductive plate installation unnecessary at the time of assembly by installing a movable contact plate as to cross the open face of a chassis at right angles and making the contact plate swing freely. CONSTITUTION:A trigger switch is composed of an insulating box body, a movable contact point 3, and a trigger lever 2; wherein the insulating box body is composed of a chassis in which a plurality of conductive plates are buried and a cover 11 attached to the open face of the chassis, the movable contact point 3 has a movable contact point facing to a fixed contact point set in a conductive plate at one end and is so installed in another conductive plate as to swing freely, and the trigger lever 2 is provided with a trigger button 20 at one end and so installed in the insulating box body as to slide freely. The trigger lever 2 which opens or closes the contact points by swinging the movable contact point plate 3 following the sliding movement is made to slide freely in the direction along the open face of the chassis and the movable contact point plate 3 is set in the direction rectangular to the open face of the chassis and made to swing freely in the installed direction of the trigger lever 2 and the cover 11 against the chassis. As a result, the assembly work is made extremely easy. |
