If you encounter issues with your Walfront RPSHK11 switch, consider the following common troubleshooting steps:
- No Power Output:
- Check if the input power sources are active.
- Ensure the switch handle is fully engaged in one of the two positions.
- Inspect all wiring connections for looseness or damage.
- Overheating:
- Verify that the load current does not exceed the switch's 63A rating.
- Check for loose terminal connections, which can cause resistance and heat.
- Ensure adequate ventilation around the switch.
- Difficulty in Switching:
- Ensure there are no obstructions preventing the handle from moving freely.
