I need some help with a strange issue.
Power always on regardless of button position. Pressing a button usually closes a circuit but here the circuit is always closed. Button moves perfectly and clicks nicely at each end of the motion. LED beside it is always-on but I'm not sure if it ever goes off - this is my only Conion.
Is it possible the switch contact broke off and is stuck closing the loop?
Or is the switch only for batteries - I've just tested on AC power so far.
