[C201/C203/C204/C-ZB-DM204] Retractive Switch Notes

Requirements

1. Retractive switches should be 2 position/way switches (i.e. bottom or top only, no middle, no 2 way/position and off)
   
2. Retractive switches should also be press to make, not press to break.
   
1. Some retractive switches have one terminal for each mode, for example the Scolmore click range seem to use L1 for press to make, and L2 for press to break.
   
1. In this case L2 should be avoided.
