I have been looking all over world after a tact switch...
It is like this type in 1100A, but i need it in Normally closed

I offer three solutions:

1) go to digikey and look up tactile switches. Select SPST-NC and view the 20 different ones they have.

2) Hire somebody to keep their finger on the button when you're not there to un-press it.

3) show us the circuit and maybe we can come up with some simple alternative that uses a readily available NO tactile switch.

Looks like I will go for your suggestion number 2
An TACT SWITCH SPST-NC IN 12x12mm like in the link, must be an special production - I have the defect switch in front of me but have no productname....
thanks anyway

I'm not recommending this site, but it does list a number of such switches:

I'd try other online retailers. Just because digikey don't have the exact part doesn't make it the last place to search. In short, expand on option 1

But, wait, what are you paying to hold that button down?
