Sequential Turn Signals
How they work...
First of
all, I would like to get you a little familiar with the parts in
this system. Even though there is only really 2 different kinds of
relays used they all serve a different purpose. |

One helpful thing to
know in understanding this system, is how to make a relay stay "on"
with just a "pulse" or closing of a switch or button for a short
period of time. The diagram to the left is an example of this setup.
Below is a description of how it works. 1. The main power is at the common terminal. 2. When switch one closes, (ven for a split second) it closes the NO contact, supplying power through Switch 2, to the coil. 3. Now the power output is "on" 4. To turn off power output, open switch 2 5. To start over, close Switch 2, and "trigger" switch 1 |
