If this pitch is widened, conventional parts cannot be used as the parts such as the contact support 5 that holds the movable contact 4. Therefore, the shape of the fixed terminals was changed in order to maintain the pitch between the movable contacts 4 at the conventional P 2 dimension. That is, the fixed terminal 13 on the power supply side has the shape shown in FIG. This fixed terminal 1
3 is a straight plate, an intermediate portion formed by bending the protruding portion of the flat L-shaped flat plate formed by forming a protruding portion at a right angle at the end portion of the flat plate by approximately 90 °, and And an extension tip portion 13A formed by bending the intermediate portion toward the outside by about 90 °, and a connection portion 13B for connecting with a terminal wiring portion is provided on the extension tip portion and the other end of the linear flat plate. The portion is provided with a fixed contact 13D. When connecting the fixed terminal 13 to the terminal wiring portion 2V, the tongue piece 13E and the protrusion 13C provided on the projecting tip portion 13A are respectively inserted into the grooves 9B and 9C (FIG. 3) provided on the case 1 to fix the fixed terminal 13 Is fixed, and the terminal screw 2A is tightened.
