The two contact portions 112 are symmetrical to each other. Are provided with a plurality of contact protrusions 113, and a plurality of, in this embodiment, two notches 114 are provided substantially in the middle of the connecting part 111. Of these, the two contact portions 112 can contact a connection terminal (not shown), respectively, thereby being electrically connected to the two connection terminals (not shown).

  Please refer to FIG. The contact terminal 12 includes a piece-like base portion 121 and an elastic arm portion 122 that is bent and extended forward from one side edge of the base portion 121. The left and right ends of the base 121 are bent downward to form a solder portion 124, and the solder portion 124 is used for soldering to other members. The elastic arm portion 122 has a contact portion 123 that protrudes downward substantially in the middle, and a circular hole 125 is formed at the end of the elastic arm portion 122. Among them, the substantially middle portion of the connecting portion 111 of the movable terminal 11 is fixed integrally with the end of the elastic arm portion 122 of the contact terminal 12 and the insulating block 13, and the movable terminal 11 and the contact terminal 12 are not in contact with each other.
