Title: Machine control circuit
Post by: andre72 on April 04, 2012, 03:32:25 AM
Hi,
Some days ago I made a circuit which turns on a relay by pressing two buttons at the same time. After some trouble with the components value it finally works!
The problem was that the relay worked by pressing one button. By using a 1,9K instead of a 2,2K it worked fine, but often failed.
So I replaced the 1N4007 with 1N4148 that should be faster. Now it really works fine.
