Re: Mechanical limit switches - acceptable practice?

The commonly available limit switches are usually rated for something like 3-5Adc with (inductive) motor loads. The stall current of a BAG motor is 41Adc. It is quite possible that the arcing that would occur as the contacts open will cause them to weld closed, defeating your protection scheme.
