Claims

[Claim for Utility Model Registration] Consisting of a retaining plate made of insulating material, a fixed contact piece and a movable contact piece attached to the retaining plate, the fixed contact piece being composed of a single metal piece, and the retaining plate a fixing plate part fixed to one surface of the fixing plate part, a fixed contact point formed on the fixing plate part, and integrally formed with the fixing plate part,
The movable contact piece consists of a fixed terminal protruding from the holding plate, and the movable contact piece is made of a single piece of metal, and is mounted on the same surface of the holding plate as the fixed plate part of the fixed contact piece. A fixed plate part, a movable part bent and extended from the fixed plate part and facing the fixed contact, a movable contact formed on the movable part and closely facing the fixed contact, and a movable part formed on the movable part and facing the fixed contact closely; a driving part formed and driven to engage with the switch driving piece so that the movable contact contacts the fixed contact; and a movable terminal integrally formed with the fixed plate part of the movable contact piece and protruding from the holding plate. The key switch contact structure consists of:
