Switch Wireing Diagram

The motor operates on low voltage DC current Robert. You will have a negative and a positive, like a car. The center connector is a common, meaning that it will be connecting to the motor whenever you switch is activated to make it go, and the other two are positive and negative to control either up or down. These should be color coded red and black and will go to the outside connectors and the remaining wire will go to the center common connection. Hook it up and then test the chair lift button. If it doesn't lift, you need to reverse the two outside wires for correct polarity, or just use the switch controls opposite; up for down, down for up.

It is just plug in connection, when you open up the hand control
