Delay switch / relay
Sorrry if this is the wrong forum section---
I have a mercury tilt switch, a battery, and a motor. The mercury switch closes the circuit when tilted at 90 degrees and again at 180 degrees. I want to add a delay/relay/circuit, so the motor only activates at the 180 degree position. HELP please!... Thanks, Mike |

I use this simple circuit alot. Play around with R and C to change time to your liking. The trick is you must use a darlington transistor.
