M mbeaver New Member Jan 9, 2008 #1 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

The trick is you must use a darlington transistor. **broken link removed** **broken link removed** Or look here: http://good-times.webshots.com/photo/2945578250085059780rPywxd?vhost=good-times Last edited: Mar 22, 2008

prprog Member Mar 19, 2008 #3 Can you post the circuit diagram again ? I do not seem to be available. Thanks.
