Where Used: On all automatic scrubbers and battery powered burnishers and vacuums. Purpose: A diode is a one-way electrical check valve that prevents electrical current from flowing in one direction. This allows us to protect a circuit and electrical components from electrical spikes. A diode also allows us to prevent back feeding of current in a shared circuit.
