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.
