A sealed electrical device like a relay includes a support base, a relay device on the inner side of the support base through which extends longitudinally-exposed terminals for feeding current to the relay device, and a housing having a relay-enclosing portion, and a stepped intermediate portion forming a continuation of the device-enclosing portion and making a face-to-face sealing engagement with longitudinally and laterally outwardly facing surfaces on the support base so that there is no straight-on access of a water stream external to said housing into the interior thereof on the inner side of the support base from either a lateral or longitudinal direction. The intermediate housing portion terminates in a sealing skirt-forming end portion extending a substantial distance longitudinally beyond the sealed portion of the support base to act as a further barrier against the ingress of an external water stream into the interior of said housing on the inner side of said support base. The support base has longitudinally extending connector guide walls on the outer side thereof enclosed by the housing skirt portion. The housing is secured to the support base by interlocking means on the inside of the skirt portion and the outside of said longitudinally extending walls. Means are provided for interlocking the housing skirt portion with a releasable locking means on the connector unit.

Sealed electrical devices

An electric shaver having two spaced shaving heads with a long hair clipper or trimmer positioned therebetween with the trimmer being adjustable to a retracted position or to an extended position in which it is spaced from the shaving heads and is adaptable to trimming sideburns, moustaches and the like. The trimmer is slidably supported on a head frame which is detachably mounted with respect to a motor enclosing housing. The trimmer is spring biased into engagement with cam means carried by the housing and adapted to position the trimmer at various heights with respect to the shaving heads. The shaving heads include foil combs carried by the head frame and spring biased against cutters which are mounted on the housing and supported for reciprocation on friction reducing ball rollers. The motor drives the trimmer and shaving cutters by means of a double eccentric carried by the motor shaft and a pair of coaxially pivoted levers which oscillate in an out-of-phase relationship.
