Louis A.M. Phelan and Clifford Hotchkiss combined their fertile minds to produce many original ideas for the control of refrigeration equipment. After applying for and receiving several patents in the area of electrical switches, they formed the Absolute Con-Tac-Tor Corporation in Beloit, Wisconsin. They were the first to effectively utilize mercury as a conducting fluid inside an evacuated tube containing contacts which became the forerunner of the thermostat of the Honeywell Corporation after they purchased the rights from Phelan and Hotchkiss. The two men also developed the first electro-mechanical switches which became the forerunners for contactor switches and relays so widely used throughout the refrigeration industry.
