There is no "on/off" condition selection. When you select a switch to operate a function, you have an "either-or" situation. The channel will be at either one endpoint or at the other endpoint. Whatever the channel is driving must be able to take the position information and use it to make an on or off operation. You cannot just plug a device into the channel for the channel to be the switch. Something must interpret the receiver's output signal and then turn the device on or off.
