Remotely controllable electrical switching apparatus
First Claim
1. An electrical switching system for controlling an electrical load, comprising:
- a remote control device capable of being actuated for transmitting a wireless control signal;
a control unit having an input for connecting to a current source, an output for connecting to said electrical load, a receiver for receiving said wireless control signal, and a switching device connected in series between said input and said output; and
, a remote switch connected in series between a signal source and a switch terminal of said control unit via a conductor, said remote switch being switchable between a first position, wherein said wireless control signal from said signal source is applied to said switch terminal, and a second position, wherein said wireless control signal from said signal source is not applied to said switch terminal, said control unit further comprising means for monitoring said receiver and said switch terminal and means for controlling said switching device for changing a state of electrical connection between said output and said input when either said wireless control signal is received by said receiver or when said wireless control signal on said switch terminal changes for indicating a change of switch position from said first position to said second position, or from said second position to said first position.

Abstract
A control apparatus for a light includes a control unit and a plurality of remote control devices. The control unit changes the state of the light, either when a conventional wall switch is actuated or when a control signal is received from one of the remote control devices, which allows the light to be controlled from a further point without the need to run additional wires down a wall to an additional switch. Each remote control device can transmit a signal to put the control unit into an ERASE mode, upon which the address codes of all remote control devices are erased from its memory, with the exception of the address code of the control device which gave the command to enter the “erase” mode. In this manner, the control unit can be re-configured remotely to respond solely to the control device which gave-the command to the control unit.

5. A control system, comprising:
-
a control unit configured for responding to a plurality of remote control devices, each remote control device of said plurality of remote control devices having an address code able to be transmitted to said control unit together with control signals, said control unit further comprising;
memory means for storing the address code of each said remote control device to which said control unit is configured to respond; and
,means for responding to an erase control signal received from one said remote control device of said plurality of remote control devices for erasing from said memory means said address code of each said control device of all remaining control devices of said plurality of remote control devices. - View Dependent Claims (6)
