I have some switches replaced by flush-mounted actuators, the installation was always without problems. The rocker switch is securely in the holder. Compared to the normal switch the rocker with the adapter is always in the center position and after pressing springs back to the center position. Normal switches remain, however in the connected end position. Combined with normal switches the actuator is a bit different unfamiliar bothers me but not, so full star number. My Conclusion: + Secure fit + Set of 3 saves packaging o return springs to the center position may look disturbing in combination with "normal" switch - Nix
