TRETAKT smart switch
This is very similar to the E2206, but lacks the parts for energy monitoring.
- Potted: tiny bit
- Module: unidentified
Remove the screw in the middle (security screw). Then use a pry tool to remove the front casing, paying attention to the raised border and the tabs on all four sides
Once inside, remove the two small screw from the main board. One corner is slightly potted, but it is quite brittle and does not really adhere to the casing. You can heat up the corner using a heat gun to make it softer.
Then firmly push on the contact pins to remove the board from its housing. Place the pins on a hard surface, then push the case down. Be aware that the switch domes must be bent inwards, otherwise they will be damaged.
