ABSTRACT:
A battery pack (10) having a protruding battery contact (14) is provided with a disconnect switch circuit. The circuit comprises at least one battery cell (22), and a mechanical switch (24) which controls .ang.operation of an electronic switch circuit (36). A latch member (16) is provided for attaching the battery pack to a device to be powered, and is moveable between a first and second position, and is biased by a spring means to the first position. In the first position, the latch member acts on the mechanical switch such that the electronic switch circuit disconnects the battery contact from the battery cell or cells. When the latch member is moved to the second position (17), the circuit operates to connect the battery contact to the battery cell or cells.
