| + | [title] Alternatively, Repair the Broken Microswitch |
|---|---|
| + | [* black] By carefully prying along a seam, it is possible to gently pry open the microswitch (i.e. it snaps together and is not glued shut). |
| + | [* black] The switch contacts (circled in red) might be dirty from grit or oxidation, causing the switch to fail. |
| + | [* black] You can clean the switch contacts by inserting a pice of paper between the contacts, then pressing the tiny plastic switch activator while dragging the piece of paper through the switch contacts (see second photo). |
| + | [* black] If the contacts were dirty, you might see evidence of this on the paper you used to clean them, as shown in the third photo. |
| + | [* black] After cleaning the contacts, use your multimeter to see if the switch now works correctly. If it doesn't, the switch may be broken beyond repair. |
| + | [* black] Before giving up, you might try using some fine grit sandpaper instead of plain paper, to clean the switch contacts. |
