Roller shutter 2, momentary or toggle switches question

[Ferran 1]

Hi.

I have purchased Roller Shutter 2 for my blinds.
The question is as follows: whether I install switches or push buttons, what happens if I connect or pulse the two switches or push buttons at the same time ?.
Do I have to install special switches or pushbuttons that, mechanically, prevent contact at the same time?
I think that nothing should happen, but I also think that the module can explode.

Thanks in advance.

I want to buy the momentary switch as well but have the same question, what will happen when both switches are held down.

Hi @mvank, @Ferran,

 

I was never able to push both at once when i tried on my model. I have ABB Swing in my model.
