Questions & Answers
NO and NO&No are two options that you can choose from The North Carolina. In the drop down menu, select the right one for you. It's unfortunate because the comments are for all kinds of switches this seller has, so most people aren't even aware that he has so many. A variety of switch styles, colors, and quantities have been commented on.
As long as the input device can function satisfactorily at three volts DC, they will work. In case the cable is long, a pull down resister may be needed.
In normal use, the magnetic piece is mounted on the door, while the sensor piece is mounted on the doorframe. As a result, there should not be very much vibration. magnet-controlled reed switch is no different from a hall effect device in that each is sensitive to impulses, but a hall effect device might be a little more sensitive. This is very easy. You might have a problem if you put the switch on the mocing part. This is not the way to use them. When the switch is within roughly one inch of the magnet, or if the parts are mounted directly opposite one another, then you might need a different technology solution. As far as I am aware, the switch does not change states if the magnet is within one inch of it. A switch indicates something else when the door opens more than an inch.

It's a good day! In case of Reed type switches, NC and NO are clear indications of what the switch is. There is an additional 1/8" of height when compared to my AEV ambulance's switches (wired). NO or NC switch with a very low current rating, this product is also able to operate as both.
I used it for dome light door switches on my UTV. Low voltage devices need relays to be run, since they are low voltage. They are really good, so I'm pleased. In case there was a problem, I purchased a few spares. You can change one out in 5 minutes no matter which one you have.
Almost all of them fail immediately. Some switches kept failing after only a couple of One suffered a short circuit at 12v @ 300mA, while the other suffered a short circuit at 5v @ 300mA.
The price is excellent while it is very adaptable to many different.
The device functioned regardless of whether it was turned on or off.
