I have some magnetic switches, so figured I'd start messing around with them. I snip and strip some wire to attach to the magnetic switch and use the switch to turn an LED on and off using both the normally open connection and the normally closed connection.

Tip: I notice you "hook" your wires onto your screws so that the open ends of the hooks face the left. If you hook the wires on the other way (so the hook faces the right when its on the screw), the hook will be pulled into the screw as you tighten the screw, rather than fighting against you and being pushed off.
I'll have to watch again. I thought I did it that way. Thanks for the tip!
That answered all my questions for an art project. Thank you.
Glad to hear! Thanks for watching!
what resistance you have used,
Hi how can i use it to an air curtain with higher wattages?
Really good and simple explanation
Woah! Never seen a gadget like youre wire stripper pistol
Can you connect both NO and NC to different lights and then have each light turn on individually? I assume this has two read switches inside.
I'm guessing it's one reed making contact with either NC or NO. I just made this video testing out using the NC and NC terminals at the same time. th-cam.com/video/T6ZCcWgAmdw/w-d-xo.html
Yes..., the two connections will do opposite, but add a relay or two, and you can do some cool stuff.
If you connected a light to each contact, NO and NC, you would always have one or the other on, but never both or neither. Unless you used a relay to reverse the function of the switch. Two switches would be better.
Sounds like Norm McDonald
Indeed!
Lol that's what I thought too!
I need to make a switch that will turn the light ON not OFF when the magnet hits the other side...is that possible, I don't have a board like that, just the switch and power lead and light. SO I need the magnet to turn on the light instead? HOw do I wire that? I need it for a game puzzle I am making for a set..where does one get the switches please? Thank you much!
If you get a switch like this one, then you can either wire it as normally closed (on) when magnet is close, or normally open (off) when the magnet is close. You just need to search for magnetic switch at any site that sells electronic components to find them.
Where did you get the wire stripper?

Is there a way to override the switch and have the light on with another switch if you choose?
Sounds like you are thinking of an OR gate. OR gate will have the load off only if both switches are off. If you turn either switch on, or both switches on, then the load will be on. All you have to do is wire the switches in parallel if they are switching the load directly.
I install one of this switch on my sliding gate to turn on a small light when the gate is open
Nice!
Can It be wired to give ground when door is open to activate a car alarm
Just wire it inline with the ground instead of the positive. The switch simply completes a circuit, it doesn't matter if it's on the ground line or the power line.
Yes, infact, switching ground is safer than power going through the cheaply made switch.
How to turn on a simple 220v bulb with reed switch ?. Guide me please.I'll be waiting
Sorry but, I don't work with high voltages. You'll have to search for "switching high voltages". Good luck!
Relays, shared ground

Where did you get the magnet switch
I got it out of radio shack's Make: it - electronics kit 2. Unfortunately, they changed the kit and didn't include this switch in the 2nd edition. So, you'd have to find the 1st edition if you wanted the kit and the switch.
You can buy them from eBay or AliExpress, and probably Amazon. Search for "door sensor magnetic switch"
