15Pcs Reed Switch with Gilded Lead Normally Open (N/O) Magnetic Induction Switch Electromagnetic for Arduino (Pack of 15) CYT1065

Update - these bounce pretty hard, some once, some 3-4 times, interval is about 50usec when pulling down an internal pull-up on an arduino nano clone digital input line. If you're triggering an interrupt with them the Isr should disregard subsequent interrupts for about 200usec.The leads are excellent and the plating makes solder flow onto them very nicely. Use a lead forming tool to bend the leads without stressing the tube - it shatters pretty easily otherwise.They do seem to vary in their sensitivity. That can be dealt with easily where you're only using one but building an array for position sensing means a lot of fiddling. Magnet size & shape are critical and that is not due to a fault with these switches but some just don't respond to the field as well as the others.Pro tip-When building a switched resistor network keep the resistors away from the area the magnet will sweep. They're magnetic.Very satisfied and will purchase again.

Excellent. The long leads are very helpful.

Decent quality. Very quiet switching (which can be annoying to some). The leads are indeed bendable and will not break the glass easily. My only complaint is maybe a short range even for a fairly strong neodymium magnet.

These were perfect for my application ( a hidden reset for my Raspberry Pi ). As with ALL reed switches make sure you bend the wire with two sets of needle nose pliers - supporting the wire .. NEVER hold the glass envelope and bend the wire.

These work great! The only critique I have is that they are terrible delicate.I snapped 2 trying to form the leads. Once installed properly, they work like a charm.
