Jerguson Model JMRS Magnetic Reed Switch

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 all SST construction and hermetically sealed reed switch provide long life at a very low cost. See Larger Image
