WebSymbol A from Figure 1 is an NC switch. A pressure rise will cause the switch to open. This would typically be applied as a high-pressure switch. If the pressure gets too high, the switch will open and shuts off the pump that is adding pressure to the system. Symbol B from Figure 1 is an NC switch with the switch arm below the terminal. WebApr 5, 2024 · A high pressure switch (HPS) and a low pressure switch (LPS) are protective devices for the compressor and refrigeration circuit.
