Abstract: A starting switch structure including a body, plunger piston movable in the body, wherein the plunger piston has a first accommodating portion at an end of the plunger piston for accommodating an end of a guide pin moving reciprocally, the accommodating portion has a butting portion at the bottom surface, an excitation portion wound around the end of the plunger piston, and a butting part at an open end of the accommodating portion of the plunger piston, wherein a contact point is led to electrically connect the first terminal to the second in case that the plunger piston and the guide pin move in a first direction when the excitation portion excites, while a broken circuit is led between the first terminal and the second terminal in case the plunger piston and guide pin move in a second direction after the excitation portion has finished exciting.
