Need Locking Switch recommendation

Heya guys,

I got few mixing tank that i need to add safety on their door to make them safe
and was thinking the best solution so far would be some Guard Locking Switch and the only brand i used so far are the one from AB like the GD2 the metal one heavy-duty.

But i was wondering if you guys knew any other product from other brand or similar that could do the job better, i need something heavy-duty.

It's gonna be used with safety relay also

Thanks !

We recently had a customer spec interlocks by Fortress.
http://www.fortressinterlocks.com

The parts we bought seemed very robust.

We've used some fortress products, their stuff is high quality and their support has always been good for us.

+1 for the fortress locks. They are super robust and the key exchange system is intrinsically safer than most.

The newer AB slamlocks are an OK copy of that system but they are not as agricultural and they are more fiddly to use (tolerances are too tight)

Thanks ! i will look at these product

These switch look very robust and good quality i will try to buy them if i got the budget Thanks for the recommendation
