Maretron Rectangular Magnetic Switch f/Indoor

The Maretron Rectangular Magnetic Switch for Indoor (MS-1035) is a compact, low-profile magnetic contact designed for door and window monitoring applications where traditional drilling and mounting hardware are impractical. This sensor leverages a specially formulated 3M adhesive tape backing that establishes a permanent bond to virtually any clean surface while remaining repositionable during the first five minutes of installation—critical when precise placement alignment is needed before final commitment.

Weighing just 0.3 lbs with compact rectangular dimensions of 4 x 1 x 7 inches, the MS-1035 delivers reliable magnetic contact technology in a form factor that minimizes visual footprint on entry points. The adhesive-mount design eliminates installation delays associated with measuring, drilling, and fastening—particularly valuable in temporary security setups, rental properties, or scenarios where surface damage must be avoided. The small profile integrates cleanly into door frames and window casings without protruding hardware that could snag clothing or compromise tactical movement.

This Maretron magnetic switch is suited for facility security monitoring, perimeter protection, building access control, and equipment-cage surveillance where passive, non-invasive sensor placement is required. It performs across interior environments where environmental sealing demands are moderate and where the adhesive bond surface is clean and non-porous. The repositionable installation window accommodates real-world setup conditions where first-attempt placement may require minor adjustment before permanent mounting.

Magnetic contact switches remain the standard for door/window breach detection in security systems due to their simplicity, lack of moving parts, and silent operation—making them preferred over mechanical tamper switches in settings where audible feedback is undesirable and reliability over decades of use is expected.
