How to use

Install the rotary switch in a suitable flush-mount wall box following local electrical codes and safety standards. Ensure power is disconnected before wiring. Connect supply and load conductors to the corresponding terminals, tighten terminal screws to the specified torque, and confirm correct polarity and continuity. After installation, restore power and operate the rotary knob to switch the connected circuit. The mechanical design provides direct on/off positions; verify operation with the intended load and check for secure electrical connections.

Recommendations

Use this rotary switch only in dry indoor environments and within the rated 230 V AC and 10 A limits. Avoid exposure to moisture or dust beyond IP20 conditions. For loads near the maximum rating, verify that connected devices do not exceed inrush current limits and consider using appropriate protective devices or contactors for inductive or motor loads. Have installation and maintenance performed by a qualified electrician in accordance with applicable regulations.
