Relay

How it works

• It takes power in one colour and passes each change on in another colour a short moment later.
• It passes changes on in order, so pulses keep their length and are only shifted later.
• Two relays in a row add their delays.
• Its coil wears the input colour, and its output wears the other.

Tips

• Use a relay to make something happen shortly after a button is pressed.
• Chain relays for a longer delay.
