It is also suitable for DIY repair and electronics projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does \"normally open\" mean for this micro switch?\u003c\/h4\u003e\n\u003cp\u003eA: \"Normally open\" (NO) means that the switch's electrical circuit is open (no current flows) in its default, unactuated state. When the actuator is pressed or triggered — such as when a microwave door closes — the circuit completes and the appliance can operate. This is a standard safety design for appliance door interlock systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the current rating of this micro switch?\u003c\/h4\u003e\n\u003cp\u003eA: This switch is rated at 16A, making it suitable for handling the electrical load of most standard household appliances. Always ensure the switch rating meets or exceeds the requirements of your specific device before installation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many switches are included in one order?\u003c\/h4\u003e\n\u003cp\u003eA: Each order includes 1 piece of the KW3A-16A micro switch.
