An electromagnetic relay (2) includes noise dampening means (20, 32, 34), such as an elastomeric insert, a noise dampening composition or material, or a resin located at the juncture between the relay armature (4) and the spring (6), which noise dampening means (20, 32, 34) reduces noise generated by contact between the armature (4) and the spring (6) as the relay (2) is energized and the armature (4) is pulled into the core (8) and when the relay (2) is de-energized and the spring (6) biases the armature (4) away from the core (8).

Un relais électromagnétique (2) comprend un moyen atténuateur de bruit (20, 32, 34), tel qu'un insert élastomérique, une composition ou un matériau atténuateur de bruit, ou une résine située à la jointure entre la palette mobile de relais (4) et le ressort (6). Ce moyen atténuateur de bruit (20, 32, 34) réduit le bruit généré par le contact entre la palette mobile de relais (4) et le ressort (6) lorsque le relais (2) est traversé par le courant et la palette mobile (4) est poussée dans le noyau (8) et lorsque le relais (2) n'est plus parcouru par le courant et le ressort (6) éloigne la plaquette mobile (4) du noyau (8).
