Hello everyone!
General question, want to see how you approach a particular problem:
I want to have an option in hardware, between this circuit or that circuit on a printed board. Say to light up an LED, I could use either PA1 or PA2 on a VIA (silly example). How can I decide in hardware how to do that?
Options (that I know of):
1) Solder Jumper. Basically some pads on one side of the board, and I either connect these two pads together, or those two pads together. This option is fairly permanent, unless you get the solderwick out.
2) 2.54 mm Jumper. Have some exposed pins, and place a jumper between them. This option is easily changeable, but I don't like that the tiny little jumper could possibly get lost. I have tiny kids, and tiny toys tend to get lost in tiny mouths!
3) SPDT switch. I use one for switching the power on or off on my board right now. This option is neat, and nothing can get lost, but takes up board space and is (relatively) expensive in comparison to the other two.
I guess there are smaller SPDT's out there like this one:

I'm looking for a "middle of the road" option. I don't like the permanence of just using solder, but I don't like the fact that tiny jumpers can be lost, and I don't like how many SPDT's are kindof big. Is there something you've seen or used that could be another option?
Thanks for any thoughts!
