A current-reversing switch having four angularly disposed bus bars separated at the inner ends thereof. A power-actuated switch subassembly including a reciprocable shaft carrying switching contacts disposed on opposite sides of the bus bars. The switching contacts are disposed out of phase so that in one position of the reciprocable shaft the contacts on one side of the bus bars are operative to effect a current flow in one direction and in a second position on the opposite side the contacts are operative to reverse the current flow through the bus bars.
