What does the constant speed control switch allow the compressor to do?

The correct response regarding the function of the constant speed control switch is that it allows the compressor to release excess compressed air when demand drops. A constant speed control switch is designed to maintain a specific operational speed of the compressor, which typically results in the compressor continuing to run at that speed even when the immediate demand for compressed air decreases. When there is a surplus of air generated but not being utilized, this switch activates a release mechanism or a pressure relief valve that ensures excess air is vented safely to avoid over-pressurization and potential equipment failure.

This operation is crucial for maintaining the safety and efficiency of the system, as it helps manage pressure levels effectively without needing to stop the compressor entirely. This choice reflects the primary role of the constant speed control in balancing output with the system’s current demands.
