Before replacing it with a new switch, reconnect the connector and press the little button to check if the lights go out. If they do then the switch is good and only needs to be adjusted. The adjustment can be done with the nut. However if the lights don’t go out the switch is bad and needs to be replaced. Sourcing a switch online at http://www.rockauto.com/ is the best way to go.
