Without knowing what's on a certain coach/year ect. You either have a continuous or latching solenoid relay. If just two wires to the front switch its cont.duty solenoid. it's switch is on /off like most switches in coach. If lamp at switch there will also be a ground wire.If many wires on back of switch like in diagram it's latching relay/solenoid.
Is there an issue your having with it , best to try to put all your cards on the table first, as someone helping may think they are done after answering first question.
