Zusammenfassung: | PROBLEM TO BE SOLVED: To reliably perform order operation of nonoverlapping contact points, and reduce dispersion of opening-closing time by setting a relative position between plural reed switches and its contact point opening-closing ring-shaped magnet in prescribed arrangement. SOLUTION: When an operational electromagnet 6 is excited, a fixed iron core attracts an armature 14 with a hinge point of a yoke 7 as a fulcrum. Therefore, a contact point rod 9 of a contact point unit 10 opens and closes contact points of reed switches 4a and 4b by a ring-shaped permanent magnet 8 against resiliencey of a return spring. At this time, the ring-shaped permanent magnet 8 and the reed switches 4a and 4b respectively regulate a relative position between the reed switch 4a for an (a) contact point and the reed switch 4b for a (b) contact point. Therefore, after a contact point of the reed switch 4b for a (b) contact point returns, the reed switch 4a for an (a) contact point performs order operation to be operated. The armature 14 completes attracting operation on the anti-hinge point side of the yoke 7. Therefore, order operation of nonoverlapping contact points can be performed. |
