PROBLEM TO BE SOLVED: To confirm on/off state of an electric power source in the dark by only touching with a hand, by projecting the head of a confirmation button from the surface of a device by a prescribed quantity by a means being operated at current flowing by turning on the power source of an electric apparatus to convert shaft rotation in the fixed direction to rectilinear displacement, and recessing it by a energizing means in the off state or at no current flowing. SOLUTION: When in the closed condition of a power source switch 14, the power source 16 of an electrical device 10 is turned on and current flows, rotation in the fixed direction of the motor shaft of a rotating means 5 is converted rectilinear displacement by a gear, and the button head part 6A of a confirmation button 6 is pushed out from the surface 12 of the electric apparatus in the projecting direction. When the power source 16 is turned off, or current does not flow by being detached from an outlet on the closed state of the power source switch 14, because force is not applied to the shaft of the rotating means 5, the button head part 6A pushed back by the spring of an energizing means 7 is retreated in the vicinity of the surface 12 of the electric apparatus. Consequently, in the dark or even in the case of a person having disabled eye, on/off state of the power source 16 can be simply confirmed.
