EE folks: what would you use for:
- a connector
- that is panel-mounted (sheet steel)
- for SELV
- for less than 5 A of current
- with a quick disconnect capability
- that isn't a banana jack or a screw?
@whitequark✧✦Catherine✦✧ cursed but some Chinese manufacturers use speaker terminals (the press and insert type) for this. I've even seen them used for 120V mains.
