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.

Dependent claims

An electrical device comprising:

a housing;
a power source comprised of a plurality of neighboring batteries connected in series and located in the housing;
an integrated circuit mounted in said housing and powered by said batteries;
and
a switch means comprising an electrically insulating barrier operatively attached to said housing and insertable between two neighboring batteries of said plurality of batteries for interrupting power through said batteries and said integrated circuit and further preventing power consumption by said integrated circuit, and an upper cover resiliently mounted on said housing for shielding said housing and operatively moving said insulating barrier from between said neighboring batteries, whereby when said cover is depressed, said insulating barrier moves from between the neighboring batteries to a position allowing a completed electrical circuit between said power source and said integrated circuit, thereby powering said integrated circuit.
