5.3 Wiring Diagrams
Important: A neutral wire (N) is required for this device. Ensure power is disconnected before wiring.
Image: This diagram illustrates three common wiring configurations for the KETOTEK Smart Switch Module. It shows connections for directly controlling a load, integrating with a 1-way external switch, and integrating with a 2-way external switch. All diagrams emphasize the necessity of a neutral wire connection.
The module has terminals for Live (L), Neutral (N), Switched Live (L1), and external switch inputs (S1).
- Connect to Load Directly: Connect the Live (L) and Neutral (N) wires from your power supply to the module's L and N terminals. Connect the load (e.g., light bulb) between the module's L1 (switched live output) and the Neutral (N) wire.
- Connect to Load and 1-Way External Switch: Connect Live (L) and Neutral (N) from power supply to module's L and N. Connect the load between L1 and N. Connect one terminal of your external 1-way switch to the Live (L) wire and the other terminal to the module's S1 input.
- Connect to Load and 2-Way External Switch: Connect Live (L) and Neutral (N) from power supply to module's L and N. Connect the load between L1 and N. For a 2-way switch setup, connect the common terminal of the first switch to Live (L). Connect the two traveler terminals of the first switch to the two traveler terminals of the second switch. Connect the common terminal of the second switch to the module's S1 input.
