  • DESCRIPTION
  • SPECIFICATIONS

The Dungs 266927 GMH-A4 ventless pressure switches are adjustable switches designed for automatic burner controls. They facilitate circuit operations based on changes in medium pressure relative to the set point, with the set point adjustable via an integrated dial. Equipped with a test nipple in the metal housing for verifying the set point, these SPDT pressure switches do not require auxiliary power.

The GMH-A4 variant is suitable for activating or deactivating a circuit when the set point is exceeded, indicated by a neon light, requiring manual reset to restore operation.
