I have a 12 volt Dayton linear actuator #4Z842 (obslolete). I am looking to put sealed limit switches towards each end of planned travel. The actuator label says 12 volt 22 amp. I read a post in here where it was stated look for a switch with that rating but I'm coming up empty handed in my search. I have the wiring diagram but can not source the darn switches. I can't even find anything in Honeywell. What I'd like to use is a sealed micro or snap switch but at this point I'd consider anything sealed that covers this power rating. Help PLEASE!
