Vacuum pressure switch normally closed adjustable

Vacuum Pump Pressure Switch

VAC-001/VAC-002/VAC-006

 Please note that the switch adjustment is done via the screw in the end of the switch as follows:

•  Anti-clockwise (screw outwards) to increase vacuum
•  Clockwise (screw inwards) to decrease vacuum

Use a make/break diode relay to the switch (as supplied in kit VAC002) – non-suppressed relays will cause damage to the switch as will excessive running of the pump due to poor plumbing/leaks.

NB  Please check that these products are suitable for your application.
