In the circuit shown in (Figure 1), the switch makes contact with position b just before breaking contact with position a. As already mentioned, this is known as a make- before-break switch and is designed so that the switch does not interrupt the current in an inductive circuit. The interval of time between "making" and "breaking" is assumed to be negligible. The switch has been in the a position for a long time. At t = 0 the switch is thrown from position a to position b.
