2.Unscrew nut securing defective switch to panel. Push switch in to release from panel. Remove nameplate from front of panel.
3.Access to rear of switch through bottom hole under front end panel.
4.Disconnect leads from switch. Tag leads as they are disconnected to assure, during replacement, they are reconnected to the proper switch terminals.
Replacement:
1.Connect tagged electrical leads to replacement switch.
2.Insert replacement switch through panel from which defective switch was removed. Insert nameplate over toggle and secure to panel with nut supplied with switch. Orient switch and tighten nut to secure in desired position.
