LTspice tutorial - Modeling Switches

In this video I look at how switches can be modeled using LTspice. Now "switch" is a very generic term - it can refer to a mechanical switch, a relay or some sort of electronic component or circuit. Based on the exact propriety that needs to be modeled there is more simple or more complex method, and I try to look at some of these.
