Abstract: An electric shaver comprises an inner case which retains an electronic part board and an outer casing which retains a plug pin board which secures a plurality of plug pins. The inner case is fabricated of a plastic integral with a bottom wall. The electronic part board is disposed above the lower separating wall while the plug pin board is disposed under the lower separating wall. Metal pins penetrating the lower separating wall connects the electronic part board and the plug pin board. The bottom opening of the outer casing is closed with a bottom cover. The bottom cover has a pair of through holes through which extend outwardly a pair of plug pins.

Abstract: The battery retaining system has a printed circuit board, a battery, and contact fittings. L-shaped contact fittings soldered to the backside of the circuit board hold battery electrode conducting tabs through slits in the circuit board. The battery is solidly retained with reliable electrical contact while minimizing the use of circuit board area. Spent batteries which arc harmful to the environment can be easily removed and recycled.
