Instead of sanitising light switches, stop having light switches. Movement sensors/Google Assistent can switch lights without any need for touching switches.
But if, like the crushingly vast majority of households and most workplaces, you do in fact have light switches, you should sanitise them.
Doorknobs are awful technology to the point that Australia recently outlawed them for new bulidings. Handles are still problematic but have a larger surface area so different people touch at different places and less pressure is also helpful.
I was using “doorknobs” as shorthand for any kind of door handle. If you have door handles, you should sanitise them. I think this is unhelpful pedantry.
