The four SPST switches in center of simulator screen represent the two plug in watt outlet in wall. Notice the brass strip between the outlets one one side has been cut. The 24 ohm resistor represents the 600 watt coffee pot that we want to remote control.
At bottom left hand side is remote control toggle switch that plugs into lower of two wall outlet plug in to complete the circuit.
At very bottom, is plug in wired together that goes in bottom plug in if you want to use the upper plug in without remote control switching.
