ABSTRACT:
The contacts of a DC contactor operating in a contaminated atmosphere are prevented from welding as a result of jamming of the armature by a thin nonmagnetic shim which is mounted on the armature so that it is disposed in the closed magnetic circuit and retains a dirt-shielding gasket above the armature pivot area so that falling dirt cannot accumulate between armature and yoke where it might, absent the gasket, interfere with closing of the armature and thus result in reduced contact pressure and increased heating of the contacts.
