Claims

[Scope of utility model registration request]

The fixed switching contacts are arranged alternately on different trajectories on the insulating plate, and the trajectories of the contact pieces of the sliders are arranged on the insulating plate between the plurality of fixed switching contacts arranged on the same trajectory. A switch characterized in that a through hole having a width wider than the width of the line is formed so as to cross the locus.
