A self-centering mechanism (200) for an appliance knob (100) includes a shaft member (202) defining a central axis, and a rotatable member (204) engaged and rotatable with the shaft member (202) aboutthe central axis. The rotatable member (204) defines a first arcuate slot (206) opposed to a second arcuate slot (208). A first stationary pin (212) extends through the first arcuate slot (206) and asecond stationary pin (214) extends through the second arcuate slot (208). A centering member (218) is pivotably engaged with the rotatable member (204) about a pivot location (220), and is configured to contact the first and second stationary pins (212,214) with the rotatable member (204) disposed in a centered rotational position. A biasing member (224) is configured to bias the centering member (218) about the pivot location (220) toward the shaft member and the first and second stationary pins (212,214) to urge the rotatable member (2049 to the centered rotational position. 一种用于电器旋钮(100)的自定心机构(200)包括限定中心轴线的轴构件(202
