What is the difference between soldering contacts and pressure contacts?

Answer 1

Soldering contacts are generally flat and designed to have a wire (or another contact) placed touching it, both heated, and solder melted over both, which will then hold them together and connect them electrically.

Pressure contacts are generally spring-loaded in some fashion, and are designed to have a object held against them somehow. The electrical connection comes from the other object being held against it. The most common pressure contacts are for batteries in most consumer devices (except Apple products and automobiles).

Answer 2

Soldering contacts involves using molten metal to create a physical bond between two materials, while pressure contacts rely on physical force to make a connection without requiring heat or additional materials. Soldering provides a more permanent and reliable connection, while pressure contacts are easier to disconnect and remove when needed.
