The Jerguson JMRS series float operated magnetic reed switch is designed to provide reliable low cost switching.  Utilizing a magnetically actuated reed switch to provide a contact, switching occurs when the float moves a magnet into close proximity of the reed switch.  The float magnet and reed switch mechanism are isolated from one another by a non-magnetic stainless steel barrier.  The all stainless steel construction and hermetically sealed reed switch provides long life at a very low cost, without diagrams or other seals that can leak.
