Reed Switch Set, 3/4" Recessed, Magnetic Switch w/ Cable Leads, Open Loop - 10 PackNPNB-130T-12
Open Loop Magnetic Switch Sets, 3/4" Recessed Press To Fit w/ Cable Leads - 10 Pack (White)
3/4" Switch, 3/8" Magnet Case For Wooden Or Aluminum Doors & Windows. This recessed "normal open" style magnetic reed switch with 22 AWG leads requires that a 3/4" hole be drilled for the switch and 3/8" hole for the magnet. The 3/4" switch mounting is desirable since the extra wire and connections can be easily inserted into the larger hole for concealment. Also, should the need arise for testing or replacement, it would be easy to pull the switch, extend the extra wire and access the original connections. Installation is further enhanced by using a smaller 3/8" diameter magnet to avoid the need to center a larger hole in a 1" to 1 1/2" thick door or window. This will allow you to offset the magnet should it be required. This switch set was developed for and should only be used in openings with wooden or aluminum frames.
You have the choice between multiple gap sizes and cable lead lengths to meet the needs of your application.
Note: Open Loop or "normal open" means the switch is open when magnet is in close proximity.
