Typically in the summer most mountains are busy and there are queues. Very hard to avoid in peak season. However buying tickets in advance doesn't mean you still won't have to wait in line. I would would until the day before to make sure the weather looks good either way.
Some mountains, like Stanserhorn near Lucerne, you can book specific times - but mostly it isn't a set time, just a ticket that would get you up that day....
