Step 7Adding the switch and the resistors
There was not very much space left in the head of my torch, so I soldered the single resistors directly to the contacts of the switch. Because the infrared LEDs need a separate resistor each, I put them on a small circuit board to keep the chaos limited.
The 12 position switch has a small ring attached with a pin that can be placed into a series of holes, allowing to limit the switching positions. I used this to set the switch to the 6 positions that I needed.
To fix the switch within the torch head I used a glue gun which worked suprisingly well. Just be careful not to glue the shaft.
Finally I soldered the wires to the LED circuit board.
After reassembling the torch it showed that all LEDs were working perfectly!
