Key Features
- Genuine OEM Structural Accuracy — Manufactured by Wacker Neuson to the exact dimensional and material specifications of the original switch support, ensuring the switch assembly seats and aligns correctly within the heater housing.
- Direct Drop-In Replacement — Engineered to match the original mounting points and bracket geometry, allowing the switch to reinstall without modification or adapter hardware.
- Broad HI Series Compatibility — Fits a wide range of Wacker Neuson diesel indirect air heaters, including the HI 110D, HI 110HD D, HI 200D, HI 200HD D, HI 300D, HI 300HD D, and HI 400HD D series.
- Stable Switch Operation — A correctly fitted switch support holds the control switch firmly in position, preventing movement or misalignment that can lead to intermittent operation or false readings on the heater's control panel.
- Electrical Safety Assurance — Proper support and alignment of the switch reduces the risk of unintended contact, loose connections, or switch failure — critical for safe, consistent operation of diesel-fired heating equipment.
The switch support is a structural bracket or mounting component that holds the control switch securely in place within the heater's control assembly. It maintains the correct position and alignment of the switch so that operator inputs are transmitted reliably to the heater's ignition and fuel control systems. When this component becomes cracked, broken, or loose, the switch can shift out of position, resulting in intermittent heater operation, unresponsive controls, or a complete failure to start — making prompt replacement essential for keeping the heater running safely on the jobsite.
