Bentronics at 141 Locust Street, Redding, California.

Once again, Bentronics has come through for me. This time, I was looking for a simple magnetic alarm reed switch, to be used as a garage door open sensor. All the big hardware stores had were entire, complicated, expensive alarm systems. None of the major stores I visited had the small electrical part I needed, but Bentronics did.
Previously, I had received a small mini computer from a Chinese company that had arrived with a power supply with an incorrect size connector on it. A quick visit to Bentronics, and I was able to pick up the small adapter needed to make the power supply usable with the device I had received - the very same day.
The major hardware stores don't carry the small magnetic switch I was looking for. The only big electronics store in town, doesn't carry the special little power connection adapter I needed. Now that Radio Shack is gone, Bentronics seems to be the only place in Redding left as a supplier of all the tiny electrical things.
