White-Rodgers offers a new line of SPST, ½” 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 ½” automatic (3F11) fan controls &
(3L11) limit controls and are offered in a broad range of temperature limit cut-outs to cover most
heating applications. The 10 new limit switches are available from your local Wholesaler.
