Switch assembly

A switch assembly, comprising:

• a switch unit comprising a button and a pivoting element extending from a height direction of the button, the pivoting element having a first contact part and a second contact part that are arranged in the height direction;
• and
• a positioning unit comprising a first positioning element and a second positioning element that are arranged in the height direction, the first positioning element and the second positioning element being, in a widthwise direction perpendicular to the height direction, movable respectively relative to the first contact part and the second contact part so as to position the switch unit in different positions;
• wherein the first contact part comprises, in a lengthwise direction of the switch unit, a protruding first contact section, a protruding second contact section, and a recessed first positioning section located between the first contact section and the second contact section, the lengthwise direction being perpendicular to both the height direction and the widthwise direction;
• wherein the second contact part comprises, in the lengthwise direction, a second positioning section, a third positioning section, and a protruding third contact section located between the first positioning section and the second positioning section;
• and
• wherein a maximum value of a force exerted to move the first positioning element out of the first positioning section is greater than a maximum value of a force exerted to move the second positioning element out of the second positioning section, and is greater than a maximum value of a force exerted to move the second positioning element out of the third positioning section.

A switch assembly of a vehicle ceiling light, comprising:

• a button having a turned-on state, an automatic state, and a turned-off state;
• a pivoting element extending from the button in a height direction thereof, the pivoting element having a first contact part and a second contact part that are arranged in the height direction, and surfaces of the first contact part and the second contact part having different contours, wherein the first contact part comprises, in a lengthwise direction of the button, a protruding first contact section, a protruding second contact section, and a recessed first positioning section located between the first contact section and the second contact section, and the lengthwise direction is perpendicular to the height direction, wherein the second contact part comprises, in the lengthwise direction, a recessed second positioning section, a recessed third positioning section, and a protruding third contact section located between the first positioning section and the second positioning section;
• and
• a first positioning element and a second positioning element corresponding to the first contact part and the second contact part, and being movable in a widthwise direction of the button, wherein the first positioning element and the first positioning section of the first contact part function to configure the button in the automatic state, the second positioning element and the second positioning section of the second contact part function to configure the button in the turn-on state, and the second positioning element and the third positioning section of the second contact part function to configure the button in the turned-off state.
