Q.17) Simplify the following circuit and reconstruct an alternative circuit having minimum switches: What is your conclusion?
Simplification shows that extra switches are unnecessary.
Simplification shows that extra switches are unnecessary.
Solution
The given circuit contains several switches (two double‐throw and two single‐throw switches) that may seem to offer independent control but, when analyzed, they can be arranged to perform the same function as a standard two‐way (or three‐way) switching system. In a proper two‐way switching setup, only two switches (both being double‐throw switches) are needed to control the lamp from two different positions. Thus, the additional switches shown are redundant and can be eliminated.
The circuit can be simplified to a standard two‐way switching circuit using only two double‐throw switches.
