Safety Features: Extra parts like a lock-out plate prevent tampering. Rear covers protect terminals from shorts and sparks.
Installation: Pick switches with mounting brackets, screws, or pre-drilled holes. Easy setup means less hassle and more security.

Application Fit: Match the switch to your use. Some are best for vehicles and boats, others for lamps or equipment.
