Flow control switch The present invention relates to a flow control switch, particularly to a flow control switch with a sensor for a flow rate of any liquid through a pipe, delivering a signal for controlling operation of a pump, with an additional manual mode allowing closing the switch for initiating generation of liquid pressure for operational and testing purposes. A flow control switch comprises a base, having a passageway and a chamber; a valve body, placed between said passageway and said chamber; an inner cover, fastened to said base on an upper side thereof and having a central hole; a central pole, attached to said valve body and passing through said inner cover, defining a vertical direction; an outer cover, mounted on said inner cover at an adjustable vertical position; and a switch assembly, having a contact ring which is mounted on said central pole and a conducting surface which is mounted on said outer cover; wherein flow of liquid pushes said central pole upward, causing said switch assembly to establish electrical contact, so that a signal indicating flow of liquid is generated, allowing for application of the flow control switch to various environments. A flow control switch comprising1. a base, having a passageway and a chamber; 2. a valve body, placed between said passageway and said chamber; 3. an inner cover, fastened to said base on an upper side thereof and having a central hole; 4. a central pole, attached to said valve body and passing through said inner cover, defining a vertical direction; 5. an outer cover, mounted on said inner cover at an adjustable vertical position; and 6. a switch assembly, having a contact ring which is mounted on said central pole and a conducting surface which is mounted on said outer cover; |
