## Description

ã€ WITH TERMINAL CONNECTOR: This RV connector switch will come with a 4 terminal connector to facilitate the installation of wires, you can choose suitable gauge wires on your own to install this heavy duty lug connector switch.

Review: Works great to run an electric over hydraulic cylinder. Super Easy to wire, because they pre install the reversing jumpers, saving time and money. the switch feels good, and has a positive return to off (center). I think this will last a while.
