How to remote control power strip?

Power strip is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket. Power strips are often used when many electrical devices are in proximity, such as for audio/video and computer systems. They are reliable, convenient and cost-effective.
But you still have to press the socket switch by hand to power up and down the devices. So how about using our rf remote control system to control the power strip? We can wire the power strip to the receiver and use remote transmitter to control it.
Now let's have a try.
First of all, we prepare things as follows:
1 x power strip
3 x lamps
1 x power plug for the receiver
Supposing the power strip is applied to powering 3 lamps up and down. Then we start wiring.
Connect the power plug wires to the input terminal of receiver, so that it can supply the power to the receiver. Connect the power strip wires to the output terminal of receiver.
Press remote button 1, turn on the power strip, all lamps will be on.
Press remote button 2, turn off the power strip, all lamps will be off.
