<p>The insulated moulded hollow casing (1) of the set, has a pair of main contact pins (21,22) held in a predetermined standard spaced relationship by a pin plug that is integral with the casing. The pin plug is of the type applicable to any standard mains socket. The charger-rectifier and associated current limiting circuitry, comprises passive electric circuit elements only, but no transformer, are housed in the body and shrouded to preclude access to any live parts. - The batteries are accommodated in a suitably shaped cavity (13) with contacts and a cover (14) which slides over the unit casing holding the batteries in place during charging.</p> |
