- The station broadcasts only on or off depending on the switch position, no signal which toggles the state of the receiver.
Small example: A lamp is to be controlled with 2 transmitters. Initial switch both the transmitter are set to Off. Now I turn to the transmitter 1, the lamp, and then with the transmitter 2 from.
I will now turn the lamp with transmitter 1 again I have the transmitter connected to the switch only to the off position and then get back into position A to ensure that the lamp is energized. This is something ugly but you get used to it.
