Product Description

KOBOLD paddle type flow switches can be used wherever a simple and economical, yet reliable monitoring instrument is required for flow switching applications.  The device operates as follows:  The paddle is fitted to one end of a balance arm which is in direct contact with a pre-stressed leaf spring.  At the other end of the balance arm is a permanent magnet.  This magnet actuates a reed contact located within a moveable housing outside the media.  The reed contact switches on or off depending on the position of the permanent magnet and the switch housing.  The status of the switch may then be used to electrically control the fluid flow.  The movable reed switch on the Kobold PSR/PS allows the contacts to be set either normally open (N/O) or normally closed (N/C).

This paddle switch is ideal for those looking for a solution to problems with boiler switches.  Many instant hot water boilers have external flow switches that can get blocked too easily.  The PSR is an ideal fix that will be durable and long lasting.

  1. really good flow sensor 5 Star Review

    Posted by on 4th May 2017

    installed easily, operated as described, seems to be very well constructed


  2. Well made switch 4 Star Review

    Posted by on 19th Jan 2017

    I was impressed with the quality of the flow switch. Would have given 5 stars but I did not read specs close enough. I needed a switch that would make and turn off at 2 GPM. Also when it would turn on it would not turn off.


  3. Not for home owners wanting to know when water flows into a hot water tank 4 Star Review

    Posted by on 6th Sep 2016

    The product is built very good, it was my fault for not understanding the GPM water flow spec clearly written on the web site. I should have known my own GPM water flow at my faucets at home before ordering. I wanted to turn on a hot water Laing circulator pump.


  4. Buy this one 5 Star Review

    Posted by on 25th Mar 2015

    Solid brass, sturdy construction, made in USA (not like the junk from China on E-Bay)
