Customer Reviews

Internal connections wrongThe n/o connection was actually n/c and vice versa on one switch out of three. It was easily remedied, but what happened to quality control? 33% Failure Rate as received. I was using one as a door switch to control steps on an RV. It caused the steps to extend when I closed the door, and retract when opened.2Work very well. Highly recommendedVery tiny sensor but work great. It response quickly and work as expected. Using it for garage door sensor5Small inconvenience but products works great and no problems after severalUsed it to make a alarm to sound an alarm and turn on a LED when our freezer door is open. Which I could move the wires to other side. Small inconvenience but products works great and no problems after several months4The wire would be better a little longerJust what I needed for door alarms.The wire would be better a little longer.5Works fine. Great for the priceThis device works great, but as mentioned in other reviews the NO and NC designation on the device is reversed so you have to be aware when wiring. Otherwise no problem. Switch trips when about 1/2 inch away from magnetic portion.4This switch labeled "Normally Open switch" is ACTUALLY Normally ClosedI bought the 10 Sets MC 32 Door Window Magnetic Switch (NO - Normally Open), they are labelled wrong. These are actually Normally Closed (NC) switches. For these switches, when the magnets are close together, the circuit is closed. Switches returned since they were the opposite of the description.1A nice switch, compact and self adhesive.I used one of these on our freezer out in the garage to announce when the door has not been closed fully, I'm really pleased with the sensitivity/action as its able to change state within a very small distance5Total failure1) All failed, could not handle 12vdc2) contacts were reversed when initially tested: NO tested as NC, and vise versa.1they workgreat product so far. they look "cheap" until getting your hands on them. They will do the job for what I do...one thing NOT to do...dont push 12v. through them...you will meld the contacts in their closed state. That is why I got 10 sets. It is always and accident due to the close proximity of work to this much power. We use them in our escape room at escapemysteryrooms.com and they work every time without fail. they are the one relay I can count on every single time.5They are not normally open.I believed these to be normally closed contacts, they are normally open. Will not work for my purpose. Everything I read when selecting them said they were normally closed.1
