Electrical relay with mounting bracket

A relay and mounting bracket combination comprising a relay having a body with longitudinal axis defined between a terminal end portion provided with one or more electrical terminal connectors and a base end portion adapted for engagement with the bracket, wherein the bracket is provided with one or more attachment features which facilitate the mounting of the bracket to an external object or surface when the bracket is engaged with the base end portion of the relay, wherein the engagement between the base end portion and the bracket is made by the inter-engagement of one or more protruding nubs with one or more constraint features thereby providing axial constraint against withdrawing of the base end portion from engagement with the bracket, said one or more nubs and one or more constraint features being configured so as to be capable of co-operating at any one of a plurality of rotational orientations of the base end portion with respect to the bracket, whereby the relay may be mounted on the bracket in a selected one of a plurality of rotational orientations.
