Type FSP float switch is designed to provide an electromechanical response to liquid-refrigerant level changes. The mechanism from H.A. Phillips & Co. can be applied to an operating temperature range of -50 to 150°F (-45 to 66°C). Suited for use with ammonia, R22 and other refrigerants, the hermetically sealed 10 A, single-pole dual-throw switch is magnetically actuated. It can be used to control liquid-refrigerant levels in flooded evaporators, transfer vessels and intercoolers.
