To solve this problem one should remember this point regarding inductor.
1) The current through the inductor does not change instantaneously. It means the current through the inductor remains same just before closing the switch and just after closing the switch. Similarly the current remain same just before open the switch and just after the open the switch.
i(0-) = i(0+)
2) At steady state the inductor behaves as short circuit.
3) At t=0 inductor act as a open circuit.
4) Representation of inductor in s domain for t>0.
