Gebildet 3sets Brown Iron Door Recessed Wired Security Window Door Contact Sensor Alarmmagnetic Reed Switch,Magnet Near - Connect Circuit, Magnet Away - Break Circuit

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.

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.

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

Window security.

Nicely made.

these items do not work properly the inner switch keep getting stuck. Why are China allowed to produce inferior items?

Sorry I have received the parcel

Utilisé sur une alarme c'est ok.

Que funcióna bastante bien y el imán tiene bastante fuerza por lo menos de 1 centímetro de distancia

Bra pris, snabb leverans och bra kvalitet. Kan inte begära mera.

Lo usato su degli infissi in PVC è mi sono trovato veramente bene. Ottimi.

Für einen Schrank habe ich Schalter gesucht der Licht im Schrank anschaltet wenn die Tür aufgeht. Hier sind die Reedschalter gut geeignet. Die Leistung reicht auch aus.Die Kabel sind etwas kurz, die sind wie angegeben, dürften aber gerne etwa länger sein.
