Customer Questions and Answers for Tact Switch (Control Panel Button) by Lg

This small, board-mounted tactile push-button switch is used on the control panel. It registers a momentary press so the control board can accept your selection. Replacing a worn switch restores reliable button response and consistent operation.

• Mounts to the user interface board and provides momentary contact when a button is pressed
• Sends a low-voltage signal to the control, enabling cycle or option selection
• Typical failure symptoms: unresponsive or intermittent buttons, needing extra force to register, stuck/always-on input, or unintended beeps/changes
• Helps restore consistent user-interface input when an individual button switch has failed

• Disconnect power to the appliance before servicing; shut off gas/water if applicable
• Access the control panel to reach the user interface board
• This is a board-level repair; note switch orientation. Replacement may require desoldering/soldering per OEM procedure
• Use ESD precautions and avoid overheating PCB pads; test button function before reassembly
