What is a KP switch?

The Danfoss KP pressure switches are used for regulating, monitoring and alarm systems in the industry. The KP pressure switches provide automatic limit protection or manual reset limit protection for pressure systems. The KP switches can be used with steam, air, gaseous and liquid media.

How do I reset my Danfoss pressure switch?

The switch comes packaged in position 1, which provides manual reset for both the low and high pressure sides of the switch. Moving the lobe to position 2 provides an automatic reset on the low-pressure side while retaining the manual reset on the high pressure side.

How does a Pressostat work?

A pressure switch is a device that operates an electrical contact when a preset fluid pressure is reached. The switch makes an electrical contact on either pressure rise or pressure fall from a certain preset pressure level.

How does a differential pressure switch work?

A Differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switch at a pre-set actuation point. This may be the difference between two positive or two negative pressures, one of each, or a positive and atmospheric or a negative and atmospheric pressure.

How does a Danfoss pressure switch work?

Danfoss pressure switches are electromechanical controls and limiters, that control the pressure of air and liquids within a given pressure range. All contact systems in Danfoss regulating units incorporate a “snap-action” system that maintains the contact force until the moment of contact break.

Should a water pressure switch be open or closed?

If the contacts are held open and there is no water pressure, attempt to cycle the switch by pulling the contacts open. This may dislodge the internal spring. If the switch closes, turn the power back on. If the contacts remain open, and there is no water pressure, the switch is bad.
