ABSTRACT:
A relay assembly is provided which is sealed against undesirable contaminants. The assembly includes a rigid housing having an opening, an electromagnetic relay positioned within the housing, and a cover membrane sealed to the housing and preventing contaminants from entering the housing through the opening. The relay includes contacts which project through the housing opening and through small contact openings, defined in the membrane. The relay assembly is assembled by pushing the contacts of the relay through the contact openings of the membrane, and then mounting the relay/membrane assembly to the housing.
