3.1 Daily maintenance points
Regular cleaning: Use compressed air to blow away dust to prevent contact oxidation.

Waterproof and moisture-proof (especially forklifts): Check whether the sealing ring is aging.

Avoid overload: Do not install high-power electrical appliances privately to prevent contact burning.

3.2 Precautions for replacing combination switches
Model matching:

The car needs to match the original part number (for example, the switch of Volkswagen models may not be universal).

Forklifts need to confirm the voltage (24V/48V) and interface type.

Installation steps:

Disconnect the negative pole of the battery to prevent short circuit.

Remove the steering wheel or instrument panel cover according to the maintenance manual.

Pay attention to the buckle of the wiring harness plug to avoid damage by hard pulling.

3.3 Purchase suggestions
Original parts vs. aftermarket parts:

Original parts (such as Toyota forklifts) are of stable quality, but the price is high.

Aftermarket parts can be selected from well-known brands (such as HELLA, DENSO).
