Structure of Electrolux washing machine door switch
The components that make up the washing machine door switch will be coordinated smoothly, helping the switch to maximize its use. The Electrolux washing machine door switch includes the following parts:
- Locking latch: Responsible for keeping the door tight when the door is closed
- Power closing switch
- Thermistor: Used to heat metal rods
- Thermistor in series with the coil of the relay
- Suction relay
- Steel core
- Metal rod: When heated, the system circuit will be closed and active
- Wheel: Rotating action, responsible for pulling and releasing the brake pin
How does the Electrolux washing machine door switch work?
The Electrolux washing machine door switch, also known as the Electrolux washing machine door lock, works on the principle of thermal expansion. The switch is designed as a fully automatic electric lock, which is responsible for seamlessly connecting electricity when you close the door or lid.
Specifically, when you press the Start button, electricity is supplied to the thermistor in series with the coil of the relay to help heat the metal rod. Once the metal rod has been heated, it will begin to expand and warp to connect with the rest of the washer’s systems to form a closed system.
When the wash is finished, the microprocessor closes the relay inside the door switch. At this time, the iron core inside the coil of the relay will move, causing the inner wheel to rotate clockwise, causing the brake pin to be pulled down. You can then open the washing machine door.
