Super simple and works (current rating is too low)

They are rated at 10 watts but unfortunately most LED strips draw over 10 watts (they are). with 18W, but the switch began to heat up when left on for 30 minutes, since it is used for closer lighting, which does not burn for a long time, everything is great!

Pros
  • Industrial Electrics
Cons
  • Crumpled

ATTENTION - TERMINAL marked NC is normally open, TERMINAL marked NO is normally closed.

Is it a language problem or is it more the Chinese? Clamps are marked FALSE. The terminal marked "NC" is normally open (the reed switch does not conduct without a magnet), the terminal marked "NO" is normally closed (the reed switch operates without a magnet). Another problem is that they have square washers on the clamps that are too small and turn uselessly in the associated channel. Also, I'm giving it two stars because they have powerful magnets that allow them to activate when the magnet…

2/5 fell out within a few days. The contacts were the opposite of what they are labeled as. Buyer Beware

I bought this set of 5 for a garage door surveillance project and after a few days was very disappointed in them. First, the polarity is wrong. NC tests as "open" and NO tests as "closed" on my system. but it doesn't matter anyway since you can use both, right? NOT CORRECT. 4 days later one of my sensors stopped working and I thought it was my wiring, software or hardware. After replacing everything, I was able to conclude that the sensor was defective. So replaced and everything worked again…

Pros
  • Industrial & Scientific
Cons
  • Unsure
