Abstract
A time detecting switch for an alarm clock comprises phase detecting type slide switches between rotatable coaxially mounted pairs of time wheels and detecting wheels which are rotated to the phases corresponding to an alarm signalling time according to an alarm signalling time setting. One of the pair of the two kinds of wheels comprises a disk of electrically insulating material having a hole therethrough, and an electrically conductive switch plate mounted on one face of the disk has an electric contacting portion which extends through the hole in the disk and bent to form a contacting face in the same plane with the other face of the disk.
