Good workmanship, housing unfortunately without quick release

I use the switch to my heating control - as a potential-free circuit was important. They occupy the individual switches with automatic Auschaltzeiten that I use around the boiler heating for up to 30 minutes to switch.

Is bad that you do not even the waterproof housing may open briefly to switch the trigger manually, since you only ever have to unscrew four ordinary Phillips screws. A quick release or rubber plug that one time could just open the case of the case would solve the problem.

That with the lack of space in the housing, I can not really understand, since you want to unlock potential things. Since it usually takes only a home and one cable.
