Gebildet 6pcs Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch, Magnet Near - Connect Circuit, Magnet Away - Break Circuit,Magnetic Switch(Cylindrical,White)

all good in an emergency allows me to cut off isolate my 52 volt e-bike battery very quickly

not fitted as yet, but items appear to be as shown.

Great product once you realise the labelling is wrong!NC so once closed light or circuit is open so light off! Once open the circuit is closed and light on.Black and Blue cut back the white!The above states black and white which is wrong!

Product as described, nice switch with good activation range and length of wire.

Window security.

Nicely made.

Bought these for use on an entry gate....the magnet part is installed perfectly aligned with the sensor part, and it couldn't sense the open/closed state until I reduced the gap to around 3-4mm....this is too little for my application and much less than the advertised distance of 10-15mm.Disappointed in that as they are useless for my application.

Used these to trigger interior lighting on a vintage car I'm restoring. They are almost invisible fitted flush and work well without being intrusive. I had to cut down the non wired magnet body a little though as too long for the door frame width, but still work OK.
