Circuit board EM relay with swivel armature - has contact mechanism with movable contact at armature end away from electromagnet

摘要

The armature (30) is swivelable and set at an end of an electromagnet (20), to whose excitation it responds. The other side of the electromagnet carries a contact mechanism (50) with a movable contact. A free end section of the armature and the movable contact (532) are coupled to both ends of a slidable card (60). The armature swivel slides the card with the contact mechanism reciprocally. In the region of the movable contact, a flexible element (53e) in contact with the card stresses it in the direction of its resetting. After resetting, there is a small gap between the movable contact and the card end part. ADVANTAGE - Compact design, long service life, high precision, and low current consumption.
