HVAC Dual Pressure Control Switch

Pressure control is required in a variety of HVAC applications to either maintain the system at a given pressure setpoint or to prevent disasters from occurring when the system pressure moves outside of its design limits.

Dual Pressure Controls combine the functions of a single high-pressure limit control and a single low-pressure control in one unit with a single pole, single throw (SPST) switch.
