Abstract

An electromagnetic relay comprises: a contact-point case (30) containing therein a sealed space (70); a pair of fixed terminals (31a, 31b), each electrically independent of each other and fixed in thecontact-point case (30); a movable contact (32) positioned in the sealed space (70); a pair of fixed contact points (33a, 33b), each respectively provided to the pair of fixed terminals (31a, 31b); apair of movable contact points (34a, 34b), each provided to the movable contact (32); and permanent magnets (55a, 55b) positioned so as to face part of a side wall of the contact-point case (30). Thecontact-point case (30) has a sealing layer (80) which is capable of sealing out the inflow of external air into the sealed space (70) and is provided on the inner surface or outer surface of a sidewall capable of inducing arcs.

Description

technical field [0001] The present invention relates to electromagnetic relays. Background technique [0002] The electromagnetic relay disclosed in Patent Document 1 includes: a container having a closed space inside; a pair of fixed terminals fixed to the container electrically independently from each other; and a plate-shaped movable contact provided in the closed space and capable of It moves so as to be respectively opposed to the pair of fixed terminals and to approach or separate from the pair of fixed terminals. Fixed contacts are fixed on the respective front ends of the pair of fixed terminals located in the closed space. In addition, a pair of movable contacts arranged to face the pair of fixed contacts are fixed to the movable contact. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 5559662 [0006] The problem to be solved by the invention [0007] However, the closed space inside the container is usu...
