Abstract (en)
[origin: EP4277058A1] A switch (100) includes a fixed-side terminal (2) having a shaft rod (9) and a spring (10) biasing the shaft rod (9), and a movable-side terminal (1) provided so as to be opposed to the fixed-side terminal (2) and including a movable electrode rod (3) which ensures electric conduction to the fixed-side terminal (2) and is contactable therewith/separable therefrom. The fixed-side terminal (2) is supported by a plurality of insulation support portions (5, 7, 15) provided at symmetric positions with respect to an axis on which the movable electrode rod (3) moves, an end of each insulation support portion (5, 7, 15) being fixed. Thus, an impact force at the time of opening is dispersed.
