The operational principle of a rapid boiling switch is similar to this: when the switch is pressed, the lever is pushed down and makes contact with a metal plate to transmit electricity from the heating wire to the thermal relay. When the water boils, it creates pressure on the metal plate, pushing the base part up. Simultaneously, it opens the lever, interrupting the power supply from the heating wire, thus cutting off power to the rapid boiling kettle.
Common issues with rapid boiling switches and their remedies are as follows:
Given its relatively simple structure, rapid boiling switches are prone to various impacts, resulting in frequent malfunctions. One common issue is pressing the switch without the kettle heating up.
The main causes of this problem include:
- Faulty connection between the metal pins on the switch base and the heating wire
- - Damaged switch lever, preventing proper closure with the base part
To fix this issue, first, turn off the electric kettle and remove this switch part for examination.
- If the connection with the thermostat wire is loose, damaged, or faulty, you should reconnect it and verify with a multimeter.
- If the switch lever cannot close tightly, remove the lever and gently squeeze the switch spring. Then reconnect the base and retest with a multimeter.
- Additionally, if everything appears normal upon inspection, it may be a faulty switch. The best approach is to replace the electric kettle switch.
Moreover, failure to tightly close the lid of the electric kettle can also render the switch inoperative. Therefore, remember to securely close the kettle lid before use each time.
Thus, this Mytour article has introduced you to the construction and operating principle of the electric kettle switch. It also shares some common switch faults and effective troubleshooting methods with you.
