A method is disclosed. The method includes attaching a light beam emitter to an electrical control assembly having at least one control member that is electrically connected to an electrical component, emitting a light beam from the light beam emitter across the at least one control member, moving the at least one control member between a first position in which the light beam is unblocked by the at least one control member and a second position in which the light beam is blocked by the at least one control member, and connecting the light beam emitter to a notification device via an electrical circuit. The method also includes preventing electrical current flow to the notification device when the at least one control member is in the first position.
