Eliwell mini low-pressure pressure switch, NO, 0.5 – 1.5 bar, automatic, SPST, 1/4" SAE flare

The Eliwell mini pressure switch was specifically designed for monitoring low system pressures in refrigeration and air conditioning systems, as well as heat pumps . With a switching range of 0.5 to 1.5 bar, this pressure switch is ideal for sensitive applications where precise and reliable pressure control is critical—e.g., in evaporator control or for protecting small refrigeration circuits .

The integrated SPST contact in NO (Normally Open) design ensures that the circuit is open in the idle state and closes automatically as soon as the preset pressure is reached. The automatic reset enables trouble-free and low-maintenance continuous operation without manual intervention.

Thanks to the standardized 1/4" SAE flare connection, the switch can be installed quickly, tightly, and without soldering – perfect for maintenance, service work, or system upgrades .
