A rocker switch provides a direct user control point for electrical operation, and this Coates lighted OEM SPDT rocker switch is designed for compatible 230 volt applications where the original switch has become worn, intermittent, or unreliable. When a visible control switch begins to fail, the heater can feel less predictable and less user-friendly than it should. The OEM fit, lighted design, SPDT format, and 230 volt relationship give this part practical value because operator switches work best when they match both the original electrical function and the intended panel experience. A properly selected replacement helps restore clearer control feedback and more dependable switching action. This type of component is especially useful when the rest of the heater remains serviceable and the weakness is centered on the control switch itself. That keeps the repair focused while improving everyday usability. Installed in the proper setup, this rocker switch helps restore dependable panel-side control and contributes to a cleaner service repair overall.
