Replace or retrofit
Your Thomson switch.
Thomson power sections are rugged. Most failures we see are in controls, the operator or the wiring between the switch and the generator. We test each piece before quoting so you only pay to replace what failed. When the switch is undersized or the parts chain is gone, we quote a replacement with matched ratings.
