Danfoss KP7W Pressure Switch is equipped with a single-pole double-throw (SPDT) switch, which means it has one common terminal and two other terminals that can be connected to either of the two. The switch’s position is determined by a combination of factors, including the pressure switch’s pre-set threshold and the actual pressure detected at the connector point. Depending on these conditions, the switch will either be in one position or the other, allowing or interrupting the electrical flow accordingly.

Features of Danfoss KP7W Pressure Switch: 

  • The snap-action function significantly reduces bounce time to an ultra-short duration, thereby minimizing wear and enhancing overall reliability.
  • Testing the manual trip function (electrical contact function) can be performed without the need for any additional tools or equipment.
  • Compact design,  Fully welded bellows element
  • high reliability in both electrical and mechanical aspects
