Good when they work..
I like the handle switches, typical of Hoover convertibles and pre-war Hoover uprights.
They're very handy, especially in tight spots when you want finger-tip control and I like the positive feel that you get in your hand.
However, there is a down side and that is when it comes to repairing them. I recall not long ago taking a similar switch apart on a Hoover 370 Junior. It required patience driving out the small rivets without cracking the bakelite/plastic and balancing the little square plate on the end of the plunger/spring on re-assembly.
The fault was merely corrosion of the curved metal contacts, both stationary and moving, due no doubt to long storage.
I've also had an air-way switch apart, similar to the one illustrated, since I needed to rewire the machine. I was a little careless and some bits flew out so patience was required to ensure correct re-assembly.
