Changeover switch LF 3319030

A changeover switch directs electrical current between two circuits, allowing an operator to select which appliance or heating element receives power. In professional kitchens, this type of switch is used where a single machine has two functions—such as a dishwasher that can run a standard cycle or a faster rinse-only cycle—or where two separate appliances share the same power supply, like a bain-marie and a display cabinet. The switch breaks the live connection to one circuit before making the connection to the other, preventing both from being powered simultaneously and avoiding overload or interference.

To use the switch, the operator turns the appliance off at the main isolator, opens the control panel, and identifies the existing changeover switch. The old switch is removed by disconnecting the wiring terminals, noting the position of each wire. The new LF switch is fitted in the same orientation, with the wires reattached to the corresponding terminals. The panel is closed, the isolator is turned back on, and the appliance is tested by toggling the switch between its two positions to confirm that each circuit activates correctly.

The switch is constructed with a green 2 pole mechanism rated for 16 amperes at 250 volts. The housing is designed to fit standard cut-outs in control panels, and the terminals accept spade or screw connections typical of commercial catering equipment. The 16 ampere rating indicates the maximum current the switch can safely interrupt, which determines the size of appliance it can control—suitable for dishwashers, glasswashers, bain-maries, and electric grills of moderate power. The 250 volt rating matches the standard mains voltage in British commercial kitchens, ensuring compatibility with the electrical supply.

This LF changeover switch fits specific models of BAGNOMARIA bain-maries, HILTA dishwashers and glasswashers, IME OMNIWASH dishwashers and glasswashers, and SILANOS display cabinets, panini grills, and sausage grills. The exact models are listed in the appliance manuals and should be verified before installation to ensure correct function and safety.

Cleaning is limited to wiping the exterior of the switch with a dry cloth while the appliance is powered off. No disassembly or internal cleaning is required, as the switch mechanism is sealed against moisture and dust. Regular inspection of the wiring connections for signs of overheating or corrosion is recommended as part of routine kitchen equipment maintenance.

The product is categorised under electrical components for professional catering equipment, specifically as a spare part for control systems.
