摘要： A contactless switch device including a reflected signal acquisition unit that acquires a reflected signal of a Doppler radar or a distance measurement radar, an approach and recede detection unit that detects an approach and a recede of a target based on the reflected signal, a target identification unit that identifies the target as a hand waving left and right, up and down, or back and forth, or a thing other than the hand based on a repeated pattern of the approach and the recede of the target, and a switch control unit that executes on-and-off controls on a switch-controlled object based on whether the target is the hand waving left and right, up and down, or back and forth, or the thing other than the hand.
