Nordyne 626616R Limit Switch L195-40F

The Nordyne 626616R Limit Switch is a temperature sensing control that regulates circuit activity on heat levels in heating equipment. it is used in furnaces and air handling units where it monitors internal temperature changes to protect heat exchangers from heat buildup. It operates through a heat-responsive element reacting to thermal expansion and contraction, with a range of L195F to 40F ensuring response during temperature shifts. Within HVAC systems it controlled operation by opening or closing the electrical circuit when limits are reached. The switch uses a 1/2 inch OD connection for stable placement in the sensing zone.
