3.1 Safety Precautions
- Ensure the power supply to the circuit is completely off before installation.
- Use appropriate tools and personal protective equipment.

4. Operating Instructions
The Kopp HK07 Surface Rocker operates as a standard electrical switch. Press the top or bottom of the rocker to toggle the connected electrical circuit between ON and OFF states. The tactile feedback indicates the change in state.
5. Maintenance
The HK07 Surface Rocker requires minimal maintenance. To clean the surface, gently wipe it with a soft, dry, or slightly damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the matte finish and material.
6. Troubleshooting
If the switch is not functioning as expected, consider the following:
- No Power: Check the circuit breaker to ensure power is supplied to the circuit.
- Loose Connections: With power disconnected, carefully remove the rocker cover and check for any loose or improperly connected wires. Re-secure if necessary.
