ELECTROMAGNETIC CONTACT DEVICE

摘要

Provided is an electromagnetic contact device allowing an alternating current electromagnet and a direct current electromagnet to be coupled to a contact support that is common to both. The device comprises: an electromagnet (12) constituted from either an alternating current electromagnet (12AC) having a mobile core or a direct current electromagnet (12DC) having an armature; and a contact support (36), which holds aligned a plurality of mobile contacts that are coupled to and driven by the electromagnet. Formed on the contact support is a coupling portion (40) constituted from a mobile core contact portion (41), a coupling spring front-end housing portion (46), and an armature contact portion (51) formed on the opposite side of the coupling spring front-end housing portion from the mobile core contact portion. The alternating current electromagnet (12AC) has an alternating current electromagnet coupling spring (56) inserted into a through-hole formed on the mounting surface side of the mobile core. The direct current electromagnet (12DC) has a direct current electromagnet coupling spring (161) disposed on the contact surface of the armature that contacts the armature contact portion.
