ABSTRACT:
A thin switch includes, (a) a rectangular insulating substrate, (b) a unitary fixed contact member comprising a T-shaped conductive thin-metal including a fixed contact, a first terminal, and a first conductive part therebetween, and (c) a movable contact member including a unitary elastic and T-shaped conductive thin-metal including a domed contact, a second terminal, and a second conductive part therebetween. The fixed contact member is placed so that the fixed contact is located roughly at the center of a surface of the insulating substrate and the first terminal is located at one edge of the insulating substrate. The first terminal is attached to the insulating substrate. The movable contact member is placed so that the domed contact is located over the fixed contact and the second terminal is located at the opposite edge of the insulating substrate. The second terminal is attached to the insulating substrate.
