A relay is an electrically operated switch that allows a low-current control signal to activate or deactivate a higher-current circuit within the machine. In floor saws and power packs, relays are used to control key functions such as motor engagement, safety interlocks, and auxiliary circuits. When a relay fails, the affected circuit may stop responding entirely or behave erratically, which can prevent the machine from starting or cause unexpected shutdowns during operation.
