Abstract (en)
[origin: US4580005A] A wash-tight electromagnetic relay having a housing including a bottom part and a cover part. The cover part includes a top side in which a spigot projecting inwardly toward the relay is formed and which defines a borehole extending through the spigot to a spigot bottom having an opening. The borehole opens outwardly from the cover part permitting a ball to be tightly pressed therein. The bottom part is sealed to the cover part by a sealing material and the relay interior is degassed to exhaust gas contaminants, filled with an inert atmosphere and sealed by the ball to prevent the entry of further gas contaminants.
