Some switches also come with waterproof or dustproof ratings, which I considered depending on the environment where I would install the switch.

Evaluating Wiring and Terminal Options

The way the switch connects to my circuit was another factor. I checked the type of terminals—whether they were solder lug, quick-connect, or screw terminals—and chose what matched my wiring skills and tools. Clear wiring diagrams or labels on the switch helped me avoid mistakes during installation.

Ensuring Compatibility with Your Application

Finally, I thought about what I wanted to control with the switch. Whether it was lights, motors, or other 12V devices, I confirmed that the switch’s ratings and functionality aligned with my needs. Considering the switch’s position operation and electrical specifications ensured reliable performance in my project.
