Abstract
The relay has a movable first contact, a second contact, and an actuating element operatively connected with an armature of the relay. The first contact is movable toward the second contact by the actuating element and dependent on a supply of current to the relay. A snap action spring connects the second contact to a housing of the relay. The second contact is positioned between two arrangements by the snap action spring.
Claims36
A relay comprising:
- a movable first contact;
- a second contact;
- an actuating element operatively connected with an armature of the relay, the first contact movable toward the second contact by the actuating element and dependent on a supply of current to the relay;
- and
- a snap action spring having a flat middle web and an angled outer web and connecting the second contact to a housing of the relay, the second contact positioned between two stable positions by the snap action spring when an angled region of the angled outer web is directed away or toward the flat middle web.
