Switch and Solder Lugs
Most switches require soldering. If they are PCB mount that is the only real option for assemblies. For wire harnesses there is the screw lug, the quick connect blade, and then there is the solder lug. They each have their pros and cons and what is ultimately best for a given application is up to the designer.

What makes solder lugs so appealing is that they are generally easy to solder during assembly and they are permanent enough to keep the switch/wire harnesses together for the duration of the product’s life.

There are two common types of soldering that are available; the straight (or Class 1), and the J-hook (Class 2 and 3). The solders all start the same way by striping the insulation off the wire and then tinning the conductor.
