Electrical load control with fault protection
First Claim
1. An electrical load control comprising:
- a housing, wherein the housing does not include a receptacle socket for receiving one or more blades of a plug;
a phase conductive path comprising a phase input terminal and a phase output terminal;
a neutral conductive path comprising a neutral input terminal and a neutral output terminal;
wherein each of the phase and neutral conductive paths is at least partially disposed within the housing, the phase and neutral conductive paths being arranged and configured to connect a source of electricity, connected to the phase and neutral input terminals, to a load connected to the phase and neutral output terminals;
a selectively operable electrical switch assembly disposed at least partially within the housing, the electrical switch assembly comprising a single-user-manipulated switch actuator and being arranged and configured to selectively interrupt at least one of the phase or neutral conductive paths to control connection of the source of electricity to the load responsive to user manipulation of the single user-manipulated switch actuator;
a fault protection device disposed at least partially within the housing, the fault protection device being adapted and configured to control operation of the electrical switch assembly in response to a predetermined fault condition; and
wherein actuation of the single-user-manipulated switch actuator operatively controls connection of the source of electricity to the load via the fault protection device by selectively inducing a simulated fault in the fault protection device, and wherein at least a portion of the single-user-manipulated switch actuator extends beyond the housing and is sized and configured to occupy a substantial portion of a single opening in a decorative wallplate.

Abstract
Electrical load controls are provided which include an electrical switch assembly and a fault protection device within a common housing. The switch assembly includes an actuator, and is responsive to actuation of the actuator to switch ON or OFF electricity to the load. The protection device automatically responds to a fault condition by overriding the switch assembly by automatically blocking electrical connection between phase input and output terminals and neutral input and output terminals of the load control. The actuator includes a single external interface element. In one embodiment, actuation of the actuator switches ON or OFF electricity via control of the fault protection device, and in another embodiment, movement of the interface away from the housing exposes within the housing an internal user interface for the fault protection device.

9. An electrical load control comprising:
-
a housing, wherein the housing does not include a receptacle socket for receiving one or more blades of a plug; a phase conductive path having a phase input terminal and a phase output terminal; a neutral conductive path having a neutral input terminal and a neutral output terminal; wherein each of the phase and neutral conductive paths is at least partially disposed within the housing, the phase and neutral conductive paths being arranged and configured to connect a source of electricity, connected to the phase and neutral input terminals, to a load connected to the phase and neutral output terminals; a selectively operable electrical switch assembly disposed at least partially within the housing, the electrical switch assembly comprising an external user-manipulated switch actuator and being arranged and configured to selectively interrupt at least one of the phase or neutral conductive paths to control connection of the source of electricity to the load responsive to user manipulation of the external user-manipulated switch actuator; a fault protection device disposed at least partially within the housing, the fault protection device being adapted and configured to control operation of the electrical switch assembly in response to a predetermined fault condition; and wherein the external user-manipulated switch actuator is coupled to the housing and configured for movement away from the housing to expose an internal user interface of the fault protection device, the internal user interface comprising a TEST button and a RESET button which facilitate user interaction with the fault protection device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
