Claims

[Scope of Claim for Utility Model Registration] (1) A push button that protrudes from one side of the case so that it can move forward and backward, and a push part made of a leaf spring that receives the pressing force from the push button in the middle part, and a movable contact at one end. A tension spring, a movable side terminal to which the other end of the tension spring is fixed, a fixed side terminal equipped with a fixed contact whose movable contact comes and goes as the push button advances and retreats, and one end of which is attached to the tension spring near the movable contact. and a compression spring that is coupled and whose other end is fixed at a predetermined position near the movable contact in the vicinity of the pusher, and the other end of the compression spring is located in the middle of the swing range of the tension spring in the forward and backward direction of the push button. In the push button switch, a bent part is provided at the base of the tension spring so that when the spring force of the compression spring is removed, the movable contact is maintained at the position when no pushing force is applied to the pushing part of the tension spring. A push button switch made up of (2) A push button that protrudes from one side of the case so that it can move forward and backward, a tension spring that is made of a plate spring and has a push part in the middle that receives the pushing force from the push button and has a movable contact at one end, and a tension spring and other parts. A movable side terminal having a fixed end, a fixed side terminal having a fixed contact whose movable contact comes into contact with and separates from the push button as the push button advances and retreats, and one end of which is connected to a tension spring near the movable contact and the other end of which is connected to the push part. A compression spring is fixed at a fixed position near the movable contact near the push button switch. When the spring force is removed, the fixed side terminal is moved against the movable side terminal in the direction of movement of the movable contact so that the movable contact is maintained in the position when no pressing force is applied to the pushing part of the tension spring. A push button switch that is placed at a different position.
