Circuit Breakers - Switcher

Basically this is a circuit composed by multivibrator transistor Q1 and Q1, the time required to activate the relay is determined by C1 and C2, of which it gives a fairly broad range microfaradios so you can experiment with the opening and closing times of doing adjustment with R1 and R2 (potentiometers), you can use a potentiometer to double that adjustment is accurate.

Coil-over should consume no more than 100 mA. and be consistent with the voltage. Be sure to see the switcher 1 for the design of the source and manner of functioning of the contacts of the relay. You may also have other uses for this circuit, your imagination and creativity have the final word.
