How to fix a Stanley fatmax spotlight

Fix A Stanley Fatmax Spotlight

First, you assume the rechargeable batteries have died, so you disassemble the device to see if you could replace them. I accidentally turned on the light while disassembling it. The sun was still shining brightly. Because the batteries were not the issue, I began my search for the root of the problem.

It wasn’t a long process. The magnetic reed switch had malfunctioned. To avoid making penetrations in the case, the Stanley designers used reed switches. The reed switched through the plastic case was triggered by magnets in the On/Off switch and the dimmer dial. It was a unique feature, and I thought it was well-designed.

Under the on/off or dimmer switch, there is no hole. Instead, the magnetic force is sensed directly through the plastic by the reed switch. Only the front and back of the case have openings, and when the flashlight assembles fully, they are both well sealed. Magnets are stored in the On/Off and dimmer switches, but neither penetrates the waterproof case.

The magnets in the On/Off and dimmer switches are strong enough to activate magnetic reed switches on their PCB directly above the switch. The broken on/off reed is in the lower center, and the two at the board’s upper edge are for the dimmer switch.

Both the intact and broken reed switches have rubber pads underneath them, whereas the broken one does not.

Your battery is in good condition if the red and green lights are on; however, your battery is dead, and you have to replace it if the lights are off.
