A2 Negative Pressure Switch 12 Volt 24VDC Single Port
A2 Pressure Switches,Gas water heater pressure switch
A2 is a negative pressure switch designed for the gas water heater with the latest patented technology, which can achieve good contact performance in a small space.
Negative Pressure Switch
The A2 pressure switch is an economical water heater air pressure switch product that adopts a classic and innovative shrapnel structure to achieve the characteristics of a small structure and large contact force, ensuring product contact reliability.
The A2 pressure switch has a compact structure and simple appearance. The cavity volume design allows sufficient air pressure changes to be efficiently converted into switch contact force.
The A2 series is a single port normally-open (NO) circuit negative pressure switch, which is a new design with new technology & affordable price. It has a good contact performance in such a small cavity.
