Frequently Asked Questions

Q: What is the difference between the Normally Open (NO) and Normally Closed (NC) positions on this switch?

A: In the Normally Open (NO) position, the circuit remains open (disconnected) until the button is pressed, at which point the circuit closes and current flows. In the Normally Closed (NC) position, the circuit is closed (connected) by default and opens when the button is pressed. This three-pin NO/NC button switch supports both configurations, making it highly versatile for refrigerators and other appliances.

Q: Is this switch compatible with my refrigerator or household appliance?

A: This three-pin button switch is designed to be compatible with most standard refrigerators and a wide range of household appliances, communication equipment, and automation devices. It operates at low voltages (below 50V AC or 75V DC). We recommend verifying your appliance's pin configuration and voltage requirements before installation.

Q: How difficult is it to install this button switch?

A: The switch is designed for straightforward installation. Its three-pin design provides stable mounting with minimal wobble, and no specialist tools are required. Most users — even those without a professional background — can fit it easily by following standard appliance switch replacement steps.
