Switch for pre-listening the alarm bell of an alarm clock

A kind of switch for pre-listening the alarm bells of an alarm clock, comprising spacer and control switch, wherein the said spacer is constructed as a lamella structure with two electricity-conductive surfaces located at each side respectively, and there is a slot positioned at the front end, whereat said slot has been folded partially in such a way that one electricity-conductive surface located in one side is able to be attached to another electricity-conductive surface located in other side, and hence make these two electricity-conductive surfaces position in the same side and, in addition, the said two electricity-conductive surface is in conjunction again with the control switch;

• where a press embossment is constructed at the center portion of said control switch, and in this way, it is applicable to accomplish the primary structure of said switch by press controlling the operation method (in either contacting or detaching) for these two electricity-conductive surfaces positioned at the same side accordingly;
• primarily, the said spacer is inserted into the battery compartment of alarm clock at a position located in-between the electrode and the battery so as to separate the electrode from the battery, and thereat said control switch is extensible installed on the packing box, and more over, by the time while pressing the control switch on packing box directly, it will be applicable to control the contacting operation of electricity-conductive surfaces positioned at the same side and hence the disconnected power for the battery originally will be supplied again to electrode at the battery compartment firstly via the control switch according to said spacer, and then energizing the clock movement appropriately to go off the alarm bell directly, thus it is allowable for a purchaser to pre-listen the alarm bells as well as realize the operating status of such alarm clock by means of an easy and convenient way.
