ABSTRACT:
An electrical contact is provided for use in an electromagnetic relay. The electrical contact includes an outer coating containing an element of the VA Group such as antimony, arsenic, phosphorus or bismuth. Thus, the electrical contact does not serve as a catalyst for oxidizing any organic gases which may be produced during the operation of the electromagnetic relay. Accordingly, oxidation of the gases is reduced, carbon generation is suppressed and high reliability of the contact can be achieved.
