1. Touch Button Switch Sensor ModuleThis module is constructed with quality materials to ensure stable performance. The touch switch has a maximum load current of 3A, and it is recommended to stay within 5A to prevent damage. When connected to relay control outputs, inductive loads, motors, etc., an absorption loop should be installed to protect the circuit. The maximum sensing distance is 8mm, and performance is achieved without any obstructions. It is ideal for touch key switch sensing applications. 2. **Upgraded FourWire Design** The touch mode of this module remains active for up to 8 seconds before automatically resetting. This design enhances stability and reliability. 3. **Wide Application** With a maximum control current of 3A and an output voltage of 30V, this module is suitable for various applications. It has three functions (A/B/C) that are fixed settings and cannot be customized by users, including the output status after poweron, and there is no option to choose between lock mode or click mode or adjust touch sensitivity. 4. **Compact and Convenient** Measuring just 20mm in diameter, this module is compact. It includes a matching cable, transparent doublesided tape, and a motherboard for easy setup and connection.
