Reed Switch Set, Miniature 3/8" Recessed w/Screw Terminals - Closed Loop - 10 Pack

Various lead times may apply to this product. Please contact us for more details.

3/8" Miniature Recessed Reed Switch Set, Closed Loop with Screw Terminals

The recessed, mini, "shortie" switch set is designed for applications where a 3/8" press to fit set is needed, but space limitations will not allow for a full length set to be installed. The installer is able to protect openings with this reed switch that otherwise would have to be secured with more visible surface mount configurations. Available in standard 1/2" + or extra wide 1" + gap, this series provides an easy answer to the difficult, high dollar window problems every installer encounters.

Note: Closed Loop or "normal closed" means the switch is closed when magnet is in close proximity.
