To provide a relay unit capable of setting freely the shape and size of an operation handle without modifying an actuator lever of a latching relay installed internally or influencing the operation of the latching relay.
An operation handle 3 is protrusively installed rigidly in the center of the oversurface of an engaging member 20 made of a synthetic resin in the form of flat plate for moving in cooperation an actuator lever 38 of a latching relay upon being engaged with the lever 38. The engaging member 20 is protrusively furnished with engaging projections 21, 21 corresponding to the forefront of the lever 38 at the two ends of the under-surface about the lever moving directions, and resilient legs 22... are protrusively aside installed rigidly at the two ends of each side face about the direction perpendicular to the moving direction. The resilient legs 22... can deflect freely with their resilience, and when the operation handle 3 is out of operation, the engaging member 20 is held in the center position so that the handle 3 is put in the neutral position, and the projections 21 are separated from the lever 38.
