Abstract
A battery charging device for use with a battery driven tool has a power source circuit and an interlock switch provided in the power source circuit. The battery charging device includes an operation panel having an operation key insertion opening and a charging plug insertion opening formed therein. A slide plate is movable relative to the operation panel between an ON position for turning on the interlock switch and for substantially closing the charging plug insertion opening, and an OFF position for turning off the interlock switch and for substantially opening the charging plug insertion opening. An operation key is adapted to be connected to the slide plate by means of a connecting mechanism. The operation key is permitted to be connected to the slide plate through the operation key insertion opening by means of the connecting mechanism when the slide plate is in the OFF position.
