E-Stop,Limit Switches - Car door open switches ?
Has this been tried ?
The switches fitted to most car door pillars are push to break, so N/C (the ones that make the interior light come on)
They are cheap
The are available almost everywhere
They are rugged
They have fixing/mounting points
They could easily be used with a hinged cover for e-stops
As for limit/Home switches, it depends on how repeatable the contact point is.
Is it worth spending a little time experimenting , or has it been tried and failed ?
I'll be making up an e-stop with one 1st
Just another of the ideas that came to me whilst trying to sleep
