Apparatus for controlling a load from both a wall switch and a local switch

摘要

A switching controller that allows a load to be controlled from either a switched wall outlet or a switch local to the load. A standard "3 way" SPDT wall switch replaces the normal SPST switch to allow for simple generation of a control pulse that is detected by the local control device to allow a change of state of the power provided to the load from either the wall switch or a manual switch directly connected to the control device.
