shuttle bus door

Hello I’d like to use this to open a shuttle bus door. It already has a switch but I want it remote. I’ve identified the wires but not sure how to connect them to this switch. Need a hold to close and hold to open. A customer bought the switch and I don’t quite understand the diagram. Any help thanks.

Do you have schematics for your bus door switch?

I don’t have them in hand. Is there any way you could tell me a generic connection? Currently it’s the type of switch you hold up to open or hold down to close.

Relay is just a switch, I’m afraid I will need a schematic to provide further suggestions.

Without schematic, I can only say usually our customer use NO & COM terminals to control target circuit connection.
