Abstract
An improved refrigerant float switch assembly includes a float chamber adapted for mounting in fluid communication with a refrigeration system, and a proximity switch assembly mounted adjacent the float chamber and having a tubular extension of the float chamber positioned therein. Improvements in the float chamber include the use of a baffle adjacent and inlet port thereof, and a float impact damper positioned inwardly adjacent the connection between the float chamber and tubular extension thereof. Improvements in the proximity switch portion of the refrigerant float switch assembly include a switch mechanism having an activating arm mounted directly thereon with the actuation of the switch being positioned internally of the assembly between the switch housing and the actuation arm therefore. In a second embodiment of the invention, a plurality of proximity switches are mounted on the switch assembly in spaced relation along the tubular extension of the float chamber.
