Changeover switch LF 3319195

A changeover switch directs electrical current between two circuits, allowing an operator to select which one powers the appliance. In professional dishwashers, this switch typically controls whether the machine runs on its primary supply or switches to a secondary source, such as a backup generator or an alternative phase. The mechanism ensures continuous operation during power fluctuations or planned maintenance, preventing downtime in a busy kitchen. Inside the switch, contacts open and close to route the current, while the external lever or knob lets the user toggle between the two positions without exposing live parts or interrupting the wash cycle unexpectedly.

To use the switch, the operator first ensures the dishwasher is powered off. The lever or knob is moved to the desired position—primary or secondary supply—before the machine is restarted. Once set, the dishwasher draws power from the selected circuit until the switch is changed again. The black build-up-resistant housing protects the internal components from moisture and grease common in kitchen environments, while the screw terminals provide secure connections that withstand frequent use.

This 2-pole switch is constructed for durability, with materials chosen to resist corrosion and heat generated during operation. The black finish is standardised for easy identification in control panels, and the compact design allows it to fit into the limited space behind dishwasher control boards. As a spare part, it replaces worn or faulty switches in specific models from AFI, EUROSYSTEM, IME OMNIWASH, NOSEM, SAB ITALIA, SO.WE.BO., and STORME, ensuring compatibility with dishwashers and glasswashers listed in the reference models.

Cleaning is limited to wiping the exterior with a dry cloth to remove dust or grease build-up. Avoid solvents or water near the terminals, as moisture can damage the internal contacts. The switch is designed for straightforward replacement, requiring only basic electrical knowledge to disconnect the old unit and secure the new one with the provided screws. It is categorised under dishwasher spare parts, specifically for control and electrical components.
