。 Figures 1 to 3 are diagrams showing one embodiment of this invention. Figure 1 is a partially sectional side view showing a state in which a fixed conductor with a small rated current is fixed to the bottom of the base, and Figure 2 is a side view showing the maximum rated current. FIG. 3 is a perspective view of the positioning recess formed in the bottom of the base; FIGS. 4 and 5 are cross-sectional views of conventional circuits; 4 is a partial cross-sectional side view showing the fixed state of the fixed conductor in the device, FIG. 4 is a diagram showing the case where the rated current is small, and FIG. 5 is a diagram showing the case when the rated current is the maximum. In the figure, 1 is a case, 103 is a base bottom, 2A and 2B are fixed conductors, 3 is a fixed contact, 8 is a screw, 9 is a spacer, and 10 is a positioning recess.
Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

In a circuit breaker in which a fixed conductor having a fixed contact at one end is fixed to the bottom of a base of a breaker case with a screw, a spacer is inserted into the bottom of the base between the fixed conductor and the fixed conductor. A circuit switch or disconnector characterized in that it has a positioning recess formed therein.
