Dishwasher KW4A(S) Micro Switch Miniature Type 125V250VAC
A microswitch is a tiny electronic switching device. It plays an important role in many household appliances like dishwasher, washing machine, gas stove,vaccum cleaner,etc. For example, in dishwashers, microswitches are installed in locations such as the tank lid and the washing chamber door. Once these parts are opened, the microswitch is automatically triggered to cut off the power supply, ensuring the safety of the user.
