  • a disadvantage is considered in this known hydraulic switch, that the pipe socket protrude relatively far beyond the switch housing, which is unfavorable for the storage and transport of the switch before installing it in a heating system.
  • the protruding pipe sockets consume space, e.g. in boiler rooms is often scarce.
  • the relatively far projecting pipe sockets are subject to increased risk of damage, which is also a disadvantage.
  • it is relatively complicated in the known switch due to the far projecting pipe socket to isolate the pipe socket with the attached to the free ends flanges and connected thereto continuing pipes or other elements of the heating system against heat loss.
