| The buzzing is caused by something vibrating from switching the current. Check where the buzzing is coming from, and see if you can find something buzzing. Do not touch hot wires. If you can find the source, you may be able to stop it with a bit of glue, crimping with pliers, a wedge, etc. Too much glue can insulate a circuit leading to overheating and maybe fire. The vibration may be inside something not designed to come apart. |
