Operation indicating device for electromagnetic relay

In a hinged type electromagnetic relay, an operation indicating device for electromagnetic relay comprising:

• a working member interlockable with an armature, said working member being positioned into a relay case within a small space above the yoke;
• and
• an indicating member coupled to said working member, said indicating member having an axis rotatably supported in a space above said yoke, said working member and said indicating member being substantially rectangular elongated plates, said indicating member having a recognizable indicating portion represented by coloring, said indicating member being rotated by said working member interlocking with said armature during the operation of said armature, the indicating portion of said indicating member thus rotated arriving at a corresponding position located immediately below an indication window formed in a case cover of the electromagnetic relay.

In a hinged type electromagnetic relay, a compact operation indicating device positioned in a case of the relay in a space separated from a movable contact position of the relay said indicating device comprising:

• a working member having one end interlockable with the contact position;
• and an indicating member having a first end rotatable about a supporting shaft mounted above the yoke;
• and a second end including a recognizable indicating position, said indicating member being connected to and rotatable by said working member while interlocking with said contact position during the operation of said movable contact position, said indicating portion of said indicating member thus rotated arriving at a position corresponding to an indication window formed in a case cover at the electromagnetic relay.
