Micro switch is small electronic switches that can be used in many household appliances. For example, in a washing machine, microswitches are commonly used to control various functions and operations of the washing machine. For example, when the lid of a washing machine is open, the microswitch can detect and automatically stop the operation of the washing machine. This safety mechanism prevents users from being accidentally injured while the washing machine is running. In addition, microswitches can be used to control parameters such as water level, temperature and wash time of the washing machine to ensure proper operation and efficient performance.
