ABSTRACT:
A degausser has a housing having two housing sections of generally tubular configurations. A support element is accommodated in the interior of the housing, and has a tubular portion and a generally flat portion. A core of an electromagnet is accommodated in the tubular portion of the support element, and a coil of the electromagnet surrounds a part of the tubular portion in the housing. The flat portion is formed with resiliently yieldable projections which engage associated recesses at the housing sections with snap action so as to connect the housing sections to the support element. Electric leads pass through an opening of one of the sections, are received in slots of the flat portion in a labyrinthine manner, and connected to a switch supported on the support element and having an actuating element passing through a slot in the housing to the exterior of the latter. The housing and the support element are of synthetic plastic material.
