This small insulated reed switch can carry up to 0.8A and 0.35A to 0.5A while switched, making it ideal for projects that require non-contact control. Reed switches are magnetically actuated electrical switches (not magically actuated, though it seems that way sometimes). When the switch body is exposed to a magnetic field, like a magnet or even a strong electrical current, two ferrous materials inside pull together, the connection closes, and current can flow. Without a magnetic field, the switch opens, as does the circuit it's part of.
This reed switch is easy to populate on a PCB and is encapsulated, making it more durable than glass reed switches. This is the same switch we trust in our LilyPad e-textile product line!
