Relay & Relay Box

Relays are electromechanical switches that use a small electrical signal to control a larger electrical load, while also offering electrical isolation and protection. They provide the ability to switch high-power circuits by using a smaller signal, making them essential components in a multitude of applications. Relay boxes are designed to house and protect relays, providing an organized way to manage multiple relays in a single system. They are often designed to provide environmental protection, and they make it easier to install, access, and troubleshoot relays in various electrical and electronic systems.
