BATTERY CHARGERS

摘要

A battery charger comprising an AC power input, isolation switching means, isolation control means, battery charging circuitry and battery receptacle, said isolation switching means substantially isolates said battery charging circuitry from said AC power input unless and until actuated by said isolation control means, said isolation switching means connects said battery charging circuitry to said AC power input for battery charging when actuated, wherein the operation of said isolation switching means being linked to the state of electrical insulation of said battery charging circuitry, said isolation control means and said isolation switching means being cooperatively configured so that said isolation switching means is actuated when said battery charging circuitry is electrically insulated from a user and said isolation switching means is caused to isolate said battery charging circuitry and said AC power input when said battery charging circuitry is not electrically insulated from a user.
