PURPOSE:To eliminate influence of the inclination of a lever on a microswitch by fixing the lever as well as a contact piece to the attaching plate and by attaching the microswitches symmetrically about the point of the said fixing point. CONSTITUTION:When the lever 1 is being released, it is made rock counterclockwise by the force energized by a spring 7, so that respective contact parts 14a and 14b of the contact piece 14 contact respectively the actuators 13 of respective microswitches 10 moving through respective holes 2d and 2e of the attaching plate 2, and the electrical circuit is closed. On the contrary, when the lever is energized downward, it rocks clockwise so that the parts 14a and 14b of the piece 14 is detached from the actuators 13 of the switches 10, and the circuit is cut off. As formerly described, because the lever 1 is perpendicular to the parts 14a and 14b, any disarrangement in the attaching of the lever 1, if occurring, does not influence the microswitches 10.
