Patent ID: 7498910

Claim:
A device comprising: a first stationary contact; a first movable arm adapted to be controllably electrically coupled to the first stationary contact; and at least three selected from the group consisting of a cam, a switch, a receptacle contact, and a transformer assembly; wherein the cam is adapted to rotate in place and positioned, relative to the first movable arm, so that at least a portion of the first movable arm moves, relative to the first stationary contact, in response to the rotation of the cam; wherein the switch comprises: the first stationary contact; a member comprising a distal end portion biased towards the first stationary contact; and the cam, wherein the cam is adapted to rotate in place so that: the distal end portion is electrically coupled to the first stationary contact, and thus the switch is closed, in response to the rotation of the cam in a first direction; and the distal end portion is electrically decoupled from the first stationary contact, and thus the switch is open, in response to the rotation of the cam in a second direction; wherein the receptacle contact comprises an arm adapted to be controllably electrically coupled to the first stationary contact in response to the rotation of the cam in a second direction and electrically decoupled to the first stationary contact in response to the rotation of the cam in a first direction, the arm comprising a first portion and a second portion extending from the first portion and adapted to be controllably electrically coupled to the first stationary contact to controllably electrically couple the arm to the first stationary contact, wherein at least a portion of the first portion extends in a direction that is parallel to at least a directional component of the direction of extension of the second portion from the first portion; and wherein the transformer assembly comprises a first opening and a first contact arm extending through the first opening of the transformer assembly, the first contact arm being integral with the first stationary contact and comprising a first portion and a second portion extending from the first portion, at least a portion of the second portion being offset from the first portion.
