ABSTRACT:
A switch of an integrated circuit includes: a housing wherein a plurality of cells connected in series are stored in a battery chamber formed in the housing, and an integrated circuit formed on a board mounted in the housing electrically connected to a power source comprised of the cells. An insulating barrier is normally inserted in between any two neighboring cells for disconnecting the power conducted through the cells for preventing power loss. An upper cover is resiliently held above the housing for shielding the housing having an actuating pawl normally engageable with a ratchet tooth formed on the insulating barrier. Upon depression of the upper cover to allow the pawl to pivotally raise and remove the barrier from the two neighboring cells for electrically connecting the cells, the power supply to the integrated circuit operatively actuates the integrated circuit such as for sounding purposes.
