You may have tried to link a button press to power on a gadget only to find that it does not appear to work. The most likely reason it appears to fail is that the power is only being sent to your gadget while the button is held down. On most occasions you will want to press a button once and switch something on.
To turn something on once
Controller Sensor > button _________________ + Counter (up to 1) Full _________your gadget you want to power
Note: You can wire into reset the Counter to turn off the power. So with this method you could have one button to turn on and another button to turn off.
For the same button to turn power on/off
Controller Sensor > button _________________ Selector move to next output
Selector A _____________the gadget you want to power
Selector B empty
