This switch is not an 1:1 direct replacement. It does not fit perfectly into the hole of the 10 series pedals. Although the switch does not snap in it fits in the pedal securely and tightly. Switching is 100% reliable. The advertised solution is absolutely road tested.
Installation instructions:
1. Open the battery door and pull the old switch out of the pedal
2. Desolder the little PCB from the switch
3. Desolder the two wires from the switch
4. Solder the two wires directly to the new switch
5. Push the new switch into the hole until it sits tightly
6. Close the battery door and test the pedal
