- Safety-Critical Electrical Component — Heater control switches are part of the ignition and safety shutoff circuit; using a correctly rated OEM switch helps ensure the heater operates safely and responds properly to operational commands and fault conditions.

The switch in a Wacker Neuson indirect air heater or direct fired radiant heater is part of the electrical control circuit that governs ignition sequencing, burner operation, and safety shutoff functions. It acts as the operator's primary interface or an internal control point to start, stop, or modulate heater output. When a switch wears out or fails, the heater may refuse to start, shut down unexpectedly, or lose the ability to respond to operator inputs — leaving crews without heat on cold-weather jobsites when they need it most. Replacing it promptly with the correct OEM component gets the heater back into reliable service.
