I once had a reed relay which I was using to dump the charge on a 47 uF polypropylene cap (low-leakage integrator circuit). After a few cycles, the reed switch welded shut permanently. I had to replace it and add a small resistor in series with the contacts to slow down the current spike from the cap. | |
