MC-38 Wired Door Window Magnetic Switch
MC-38 wired door/window magnetic switch for security and automation projects—triggers digital output when doors or windows open.
The MC-38 Wired Door Window Magnetic Switch is a reliable and simple sensor designed for security and automation systems. It consists of a magnetic reed switch and a magnet, which together detect the opening or closing of doors and windows.
When the door or window is opened, the magnetic field is broken, triggering a digital signal output. The switch is compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and standard alarm systems, allowing easy integration into DIY or professional security projects.
Its compact design, low cost, and easy installation make it ideal for home security systems, burglar alarms, smart home automation, and access control systems. The MC-38 provides reliable and maintenance-free operation for long-term use.
