Limit Switch · Open on Rise 200 degF Close 160 degF 2-Terminal - Alltemp 19-LS2-200
Two-terminal snap disc limit switch for temperature control circuits in HVAC and heating equipment. Opens at 200 degF (93 degC) on temperature rise and typically recloses at 160 degF (71 degC) as temperature falls.
What this product is for
The Alltemp 19-LS2-200 is a two-terminal limit switch used to interrupt a control circuit when equipment temperature rises to 200 degF (93 degC). It is commonly used in furnaces, unit heaters, fan controls, and other temperature-sensitive HVAC or heating assemblies.
Use for
Use for replacement or service work where the original control is an LS2 series open-on-rise limit switch with a 200 degF opening point and approximately 160 degF (71 degC) closing point. Typical applications include over-temperature protection and temperature-based switching in OEM or service assemblies.
Avoid for
Avoid using this part where a different temperature setpoint, terminal configuration, mounting style, or electrical rating is required. Do not substitute based on temperature alone without confirming the original part number and equipment requirements.
Best for
Best for HVAC technicians, burner service contractors, and maintenance buyers replacing an Alltemp LS2 series limit switch in existing equipment. It suits applications where a simple automatic reset snap disc control is required.
Installed in
Typically installed in warm air furnaces, heating cabinets, fan and limit control assemblies, and other equipment that needs a fixed temperature safety or operating limit. Actual fit depends on the original control design and mounting arrangement.
Why this product exists
This switch helps protect equipment from overheating by opening the circuit at a fixed temperature threshold, then allowing the circuit to reclose after the temperature drops. In trade use, fixed-temperature limit switches are commonly selected to match the OEM control sequence and safety design.
Compared with similar products
Compared with fan switches, this LS2 model is a limit switch designated to open on temperature rise. Compared with other LS2 variants, the key buying difference is the 200 degF opening temperature. Always match the temperature rating, terminal count, and original application before ordering.
