4. คำแนะนำในการตั้งค่า
4.1. Power and Load Wiring
Ensure the module is powered with the correct DC voltage (5V, 12V, or 24V) corresponding to your specific module version. Connect your loads to the relay terminals. Each relay has three terminals: Normally Open (NO), Common (COM), and Normally Closed (NC). Refer to the wiring diagram below for proper connections.

5. คู่มือการใช้งาน
5.1. Connecting to the Module
- Ensure the 4-Way Bluetooth Switch Module is powered on.
- Enable Bluetooth on your Android smartphone.
- Open the installed control application. The app should automatically detect and connect to the module. If not, check the device list within the app to select your module.
Figure 4: App Connection and Device List
5.2. Controlling Relays
The app provides an interface to control each of the four relays. You can switch them ON/OFF individually.
5.3. Setting Operating Modes
The module supports three main operating modes, configurable via the app:
- โหมดเขย่าเบา ๆ: The relay activates only while the button in the app is pressed and deactivates upon release.
- Self-lock Mode: Pressing the button toggles the relay state (ON/OFF).
- โหมดอินเตอร์ล็อค: Only one relay in a group can be active at a time. Activating one relay will deactivate any other active relay in the same group. This is useful for applications like motor forward/reverse control.
