Shorted Reed Switch
Shorted Reed Switch
(OP)
I have a reed switch that has been working properly for multiple cycles, then out of the blue it is showing a short circuit. The reed switch itself has been soldered to a circuit board and embeded in epoxy, so I do not have the luxury of being able to physically touch the switch or board.
Has anyone seen an effect on a reed switch that would cause it to suddenly short for no good reason, then remain shorted indefinetly even though there was no magentic field present?
Is it possible for a voltage spike to cause this? What else could cause this effect?
Does anyone have an idea as to what this could be?

RE: Shorted Reed Switch
Maybe a metal part inside the switch broke or came loose due to fatigue, wear or a voltage spike and now bridges the contacts in the switch, or a spring failed allowing the contacts to permanently become grounded.
