SM-226L-3Q Seco-Larm Overhead Door Mount N.C. Magnetic Contact w/ 3 Wires for N.O./N.C. Applications (One Pack)

Todo bien

Used it to replace my ADT floor switch that went out. Was nice having the option to use as NO or NC as I didnt know what my existing switch was. Easy to install and work good. I wasnt going to replace the magnet but this one was a lot nicer so I opted to use it.

Great purchase.

Nice unit, solid construction

Using as a sensor with a Raspberry Pi. Working perfectly so far. Straightforward install.

Extremely good quality. This is a robustly built product. I have two in service. Installed with no issues. Flawless operation. Good range of detection l, which eases installation.

Works as expected. Used it to automate my garage door with a Raspberry Pi. Now garage door knows position when I give the command to open or close vs just actuate.

Had one installed, but it split in half from winter weather freezing it

MUY BIEN

Worked great
