The 12V 1 Channel Latching Relay Module with Touch Bistable Switch & MCU Control is designed for reliable, stable, and efficient switching operations in automation and power management systems. Featuring MCU-based control, it provides excellent stability and anti-interference capability, while the self-locking bistable function allows easy ON/OFF toggling using a single button press. Equipped with a high-quality SONGLE relay, it supports AC loads up to 250V/10A and DC loads up to 30V/10A. The onboard touch switch allows direct manual control, and the module also supports external low-level triggering from microcontrollers or sensors. Built on a durable double-layer PCB with reverse polarity protection and voltage regulation, this relay module is perfect for smart home automation, industrial equipment control, and high-voltage switching applications.
