Without the use of electronic components, try these.
1. First analyse what u want from/ or what u are
controlling from control ckt.
2. Clearly understand the meaning of,
A) Contractor - main contact, Aux. contact & coil
B) Relays - Same as above
C) Isolator -
D) NO/ NC/ On dealy, OFF delay.
Combination of these components basically makes a control
circuitary.
