Description
White-Rodgers offers a new line of SPST, 1/2" snap disc, manual reset limit switches designed for safety in gas fired furnaces, unit heaters, and roof-top units.

Furnace designs over the last 10+ years have been required to have 2 or more of these manual reset limits inside the furnace to cover safety concerns and prevent flame rollout conditions.

This new line of limit switches complements our existing line of 1/2" automatic (3F11) fan controls & (3L11) limit controls and are offered in a broad range of temperature limit cut-outs to cover most heating applications.
