Description
The York S1-025-43201-000 SPST Limit Switch is a unique part that is used in the HVAC system to regulate electrical circuits depending on temperature changes. It works like a Single-Pole, Single-Throw switch in that it has one input and one output terminal. When the temperature of its working range of 26°F to 38°F is attained, the switch turns on to close the electrical circuit and send a signal to a control system. Firstly, it controls temperature to the nearest degree possible, and vital systems are not over or underworked. This can help avoid cases where equipment gets destroyed, save on energy, and enhance on performance of the system.
