Title:
ELECTROMAGNETIC RELAY
Document Type and Number:
WIPO Patent Application WO/2019/131432
Kind Code:
A1
Abstract:
An electromagnetic relay for detecting a mismatch between the contact (or separation) timing of a movable contact point on one side with a fixed contact point on said one side, and the contact (or separation) timing of a movable contact point on the other side with a fixed contact point on the other side. In this electromagnetic relay, a displacement part (90) of a movable contact section (9) is connected so as to be electrically continuous with a pair of movable contact points (M1, M2). An armature (3) drives the movable contact section (9). An adsorption site (AD1) on the armature (3) adsorbs an electromagnet (E1). The interior space of an opening section (842) that exposes a section (exposed section 94) of the displacement part (90) intersects with a prescribed plane (P1). The prescribed plane (P1) is orthogonal to an alignment direction (first direction D1) along which the pair of movable contact points (M1, M2) is aligned, and passes through the center (C1) of the interval between two ends (T1, T2) of the adsorption site (AD1) in the alignment direction.
