This manual limit switch is a vital safety component designed for HVAC systems, furnaces, and air handlers. Functioning as a high limit control switch, this fan disc style device monitors internal temperatures to prevent equipment overheating and potential fire hazards. When temperatures exceed the safe operating threshold, the single-pole (1P) switch breaks the electrical circuit, shutting down the heating element or burner. This manual reset model requires a physical intervention to restore power, ensuring that the cause of the temperature spike is investigated before the system resumes operation. It is an essential replacement part for maintaining the safety, reliability, and longevity of residential and commercial heating units.
