Repair Wiring for Tandem Stack Switches
How Can I Replace an old Tandem Light Switch? How to Wire a Tandem or Double Switch.
Repair Wiring for a Tandem Double Light Switch
I have a light in our foyer controlled by 3 switches. Any one can turn the light on and off.
The switch by the front door also controls the ceiling fan. It is broken. It is a vertical with two toggles that flip horizontally. The switch appears to be old school. The insides don’t match the switches I have been sold. None of the replacements work. The fan runs with the light on no matter what. The other two switches stop working entirely. Any thoughts on getting an old school switch like this? There is no part number or any id number on it. On the old switch, right side, top to bottom it was white, red, and black wires. On the left top to bottom it was black and black.

Stack and Tandem Switch Wiring
- Steve, I believe that you are describing a tandem or stack switch which is controlling the ceiling fan which should be controlled independently from the other switches.
- Depending on the actual wiring scenario, the power and travelers must be identified in order to get the right wiring configuration.
- Check out the links below to see the examples of wiring diagrams which will be helpful for this stack switch application, understanding that the stack switch can be treated as if it was actual two separate switches except that the stack switch has the capability of mechanically linking the power to be shared by both switches or to have the link removed to enable two separate power sources.
