ABSTRACT:
A button battery is installed in a electronic device such as a signal transmitter and electrically connected by a terminal contacting a flat electrode terminal of the button battery. The terminal has a circular spring-contact member surrounding a terminal base, and the spring-contact member is connected to the terminal base by a pair of connecting portions. The terminal base is fixed to a substrate by soldering. Since the spring-contact member is formed in a circular shape, its length can be made sufficiently long to make its spring modulus low and to reduce spring-load imposed thereon, thereby avoiding plastic deformation of the spring-contact member. The terminal base soldered to the substrate is prevented from being peeled off by eliminating twisting force applied to the spring-contact member.
