How can I reverse polarity for this switch when operating 12v actuators? Do I have to have an external switch?
Please see following topic for details.
And let me know in this topic (your own one) if you have other questions, thanks.
Are these relays built in the switch. If so, how should they be wired. The link you sent me appears to be external relays.
The relays in photo, in that topic are our onboard relays, please read carefully as it shows the wiring in that topic.
Also one of our customer has uploaded a Youtube video at following, it maybe helpful.
