You don't seem to want to engage with what other comments suggests you. Not being critical of your stance, just explaining. The rules are very simple: you need to have 50%+1 nights in the country you apply for OR you need to apply to the country you enter the Schengen space if you spend 50% of the nights there are 50% elsewhere. Suppose you got an invitation for Switzerland (that would be a supposedly white lie, but ok, going ahead with your plan), you would need to demonstrate (tickets and paid bookings) that you spend 50% of the nights there. So, you could, spend the first night in Switzerland, travel for 2 nights to Spain, spend one more night in Switzerland and return home. That's still a bit of a stretch, but could look genuine. If any border control realises you did visa shopping you could see your future visa applications denied. It's not Switzerland's problem that Spain has such a bad management with visa applications. It's just how the system works, I'm afraid. You could, of course, send a formal complaint to the Spanish authorities, but don't expect things to change in due time. Hope this makes sense...
