- acidburnNSA 3y agoNever, at least that I've noticed. I guess it'd be hard to tell if I missed any doorbell rings technically.
- fullstop 3y agoNo, in the cases that I'm talking about it gets stuck in one position. If you google "reed switch stuck" you'll see what I'm talking about. I figured that a hall sensor has no moving parts so it should last essentially forever.
- squarefoot 3y agoWhen contacts, including reed switches, normal switches, relays, etc, get stuck, it usually is because of sparks due to voltage spikes that weld the contacts together. this happens when contacts are used with high currents/voltages and/or inductive loads, and can be avoided using so called snubber networks. https://en.wikipedia.org/wiki/Snubber https://en.wikipedia.org/wiki/Snubber
- fullstop 3y agoAh, that's interesting. So for OP's purpose it will likely run indefinitely since there's essentially zero load.
