摘要： PURPOSE:To provide a watch switching mechanism, which is excellently usable with the use of a simple construction irrespective of the time correcting direction of hands by operating a movable contact spring constituting the switch through a proiecting cam which is made rotatable together with a minute hand. CONSTITUTION:A movable contact spring 17, which is normally connected with a stationary contact spring 18, is connected with the other stationary contact 19 by the projection 7 of a projecting cam 8, which is made integral with such a minute hand 5 as is turned once a minute in a preset direction, thereby to change over a switch. As a result, a transistor 22 is rendered inconductive to interrupt the sound generation of a sound generator 21, which has been generating the sounds in accordance with the capacity of a capacitor 24 connected with the spring 17, so that the capacitor 24 is charged. By the use of the switching mechanism using the projecting cam and the movable contact spring, the hand turning direction for the time correction is not restricted so that the usability of the watch can be made excellent with the use of such simple construction.
