The LiftMaster 41A4166 Lighted Push Button is a hardwired, momentary-contact wall control for garage door openers. Designed as a simple open/close station, it illuminates for easy location in low light and connects with two low-voltage wires directly to the operator’s wall control terminals. Because it is a wired switch (not wireless), no radio frequency pairing is required; it uses the opener’s control circuit power, typically around 24V low voltage, to operate. This replacement part is ideal for adding a basic door control near a service entry or as a straightforward upgrade from a worn or non-illuminated button.
The 41A4166 is commonly compatible with most LiftMaster, Chamberlain, and Craftsman residential garage door openers that accept a standard 2‑wire, normally open push button, including many Security+ and Security+ 2.0 models; it will open and close the door but does not provide advanced wall station features like light or lock functions. Installation is simple: run two conductors from the button to the opener’s wall control terminals (often marked red and white), observing that polarity is not required for a basic push button. For safest results, power down the opener before wiring, mount the control out of reach of children, and use indoors in dry locations. No programming steps are needed once the wires are landed, making this a practical universal-style wired door control for replacement or secondary control points.
