June 19 Information
If I have a reed switch inside a plastic box, I can actuate the switch with a magnet on the outside of the box. Can I do that if it is a metal box (sheet steel)? I suspect not, but thought I'd ask. If the steel box can work conditionally on the magnet being stronger, that is ok. Application: electronic lock. Thanks. 2602:24A:DE47:BB20:50DE:F402:42A6:A17D ( talk) 00:05, 19 June 2020 (UTC)
- Sheet steel is surprisingly bad at stopping the field from a magnet. You might be able to use the same magnet, but might need a stronger magnet. --

- Thanks, I'll give it a try when I can.
