There are two main types of pressure switches: mechanical pressure and electronic pressure switches. A mechanical pressure switch has a mechanical pressure-sensing part that deforms according to the fluid pressure.

Q830 series dual pressure controls can be not only used in fluorinated refrigerant, but also in the air
and liquid (allowed liquid temp. -20 to 120°C)
Adjustable range and differential settings.
Renovated SPDT micro-switch ensures the reliable switch function.
Flexible mounting bracket suits various kids of application.
Upper lid is optional (IP44)
Various connections are available on request.
Automatic and manual reset version
The material of bellows is copper and pressure interface is brass.
CE approval
