Abstract
A time detecting switch for a time signalling clock having a time wheel and detecting wheel both rotatably mounted coaxially and a phase detecting type slide switch between the time wheel and the detecting wheel comprises one of the wheels comprising an electrically conductive hub having a flange with a radial contacting surface at one end of the hub, an insulating disc and a sectoral switch plate around the hub, the disc being sandwiched between the plate and the flange with the plate being mechanically and electrically connected to the other end portion of the hub facing the other wheel. The other wheel has a sliding contact for contacting the sectoral plate and the radial contacting surface of the flange is capable of maintaining uninterrupted continuous sliding contact with the signalling circuit of the clock.
