Summary:PURPOSE:To turn an indoor lamp switch off even when there is abnormality in a hook by mounting a switch member conducted with one pole of the indoor lamp switch engaged with a hook member and moved, a terminal member conducted with the other pole connected to the switch member and a torsion spring to the switch member. CONSTITUTION:The rotary base section of a switch lever 42 is formed so as to be rotated centering around a rotary support shaft 46 installed into a switch body 40. The rotary base section of the switch lever 42 is turned and energized in the direction separated from a terminal member 41 at all times, the counterclockwise direction, by a torsion spring 44 set up to the rotary support shaft 46. When the switch lever 42 is pushed toward the terminal member 41 by the pushing section 17d of a hook 17, the switch lever 42 is revolved in the clockwise direction against the torsion spring 44, and a projection 42a for electric conduction is brought into contact with the terminal member 41. An indoor lamp is supplied with fixed currents, and lit. Accordingly, a switch SW can be tuned off even when abnormality is generated in the hook section 17.
