Self-locking relay module, electronic components, 5V simple and bistable SCM control board

Features: 1. Wide Applications: Used for controlling household appliances, various lamps in the home, and factory equipment; suitable for controlling various high-voltage, high-power, low-current components. 2. High Performance: Utilizes a single-chip microcomputer for control, ensuring stable and reliable performance, strong interference resistance, and no false triggering—far superior to the CD4013. 3. Stable Operation: The high-power voltage regulator tube provides sufficient and stable voltage, and ample heat dissipation holes ensure stable and reliable operation over extended periods. 4. Protection: Equipped with a power supply protection diode to prevent reverse polarity, short-term reverse power supply interruptions will not damage the self-locking relay module. 5. Easy to Use: The trigger can also be connected to an external trigger switch. The self-locking relay module is equipped with a terminal block and a lead wire, making it more convenient to use. Specifications: Item Type: Self-locking relay module Material: Electronic components Panel Design: Dual-panel PCB design Supply Current: Greater than 100mA Load: 250V 10A AC or 30V 10A DC How to Use: Press the trigger button, the relay is closed and locked; press it again, the relay is disengaged. It can also be connected to an external trigger switch and a low-level trigger. Package List: 1 x Self-locking relay module Note: The power supply is as required by the wiring diagram and cannot be reversed. Although there is a protection circuit, it cannot be reversed for extended periods.
