A light guide part () is provided along a Z-axis on a side surface of a case () of a relay (). The light guide part is a thick portion formed of a material forming the side surface of the case, and is structurally integral with the other parts of the case. Also, a light emitting device which emits light in response to application of a voltage to coil terminals () is provided within the relay () (case). A reflection surface () which reflects illuminating light emitted from the light emitting device in a (+Y) direction in a (+Z) direction is placed at a lower end of the light guide part. Illuminating light reflected by the reflection surface is guided to a display surface () placed at an upper end of the light guide part, to illuminate the display surface.

Relay

In a relay ( ), right and left sides of an edge on an upper end side of an L-shaped armature ( ) are bent to form an engagement portion ( ) and the armature is held to be rocked and displaced through an energizing spring piece ( ) of a hinge spring ( ) in a state in which the engagement portion ( ) is engaged with an edge portion of an end face on an upper end side of a core ( ). During magnetic adsorption, moreover, an upper end of the armature ( ) has an outer peripheral surface thereof to abut on the end face ( ) at the upper end side of the core ( ) in a close contact state.

Relay and method of manufacture thereof

An operation indicating device for electromagnetic relay which comprises a working member interlockable with an armature of an electromagnetic relay and extending into a space above a yoke, and an indicating member coupled to the working member and having an axis rotatably supported in the space above the yoke, the indicating member having a recognizable indicating portion and being rotatable by the working member interlocking with the armature during the operation of the armature, the indicating portion of indicating member thus rotated arriving at a position corresponding to an indication window formed in a case cover. When the armature is activated, the working member, interlockable with armature, is activated and the indicating member coupled to the working member is rotated around a supporting shaft serving as the fulcrum. The indicating portion of the indicating member moves to a position located immediately below an indication window formed in the case cover and the operation of the electromagnetic relay can be visibly confirmed.
