Stuff for building automation panels is screwed up. Various sizes of phoenix terminals are in short supply. Siemens brand buttons, switches, and LEDs are in short supply, so we end up putting white LEDs in things because green is not available. Don't have any 2 position switches, so we'll use 3 position and try to make it work. Some of the order times are in months. If you order 2-position Siemens switches right now, you'll get them in 3 months.

I mean switches like this: https://www.amazon.com/Positions-Maintained-Operation-Switching-Operating/dp/B008TT9C6M

Cheap knockoff amazon garbage is still available, but it's probably not a good idea to install that in a panel that costs money and is expected to last for 20 years with no maintenance.

Also certain sizes of sta-kon ring terminals and fork terminals are hard to get. It takes a month to get blue fork terminals for some reason. Cheap shitty Amazon ones still exist, but I wouldn't trust those. There's probably a reason they cost so little.
