-1- ABSTRACT A grounding switch for a main power circuit includes a resistance contact unit and a short circuiting contact unit accommodated in a single sheath. A movable contact of the short circuiting contact unit is connected to a movable contact of the resistance contact unit and a fixed contact of the short circuiting contact unit is grounded. A resistor is connected between the movable contact of the resistance contact unit and fixed contact of the short circuiting contact and is temporarily inserted into the main power circuit when the resistance contact unit is closed. The resistance contact unit and resistor are arranged on parallel axes in the same sheath thus simplifying the construction.
