Light adjusting device

A light adjusting device, comprising a housing, a light adjusting assembly and a circuit switching mechanism, wherein the light adjusting assembly comprises:

• a first potentiometer connected to a first electrical circuit to control a light adjusting function of the first electrical circuit, a second potentiometer connected to a second electrical circuit to control a light adjusting function of the second electrical circuit and an operating structure which is connected to the first potentiometer and the second potentiometer for adjusting the light adjusting function of the first potentiometer and light adjusting function of the second potentiometer;
• wherein the first potentiometer and the second potentiometer comprise linear slide potentiometers that are electrically connected in series and the operating structure comprises a first push rod mounted to handle of the first potentiometer and a second push rod mounted to a handle of the second potentiometer;
• the circuit switching mechanism is configured to connect the light adjusting assembly to one of the first electrical circuit or the second electrical circuit, the circuit switching mechanism comprising a rocker, a spring, an ejector rod, an actuating member, a mounting seat, and a first side contact (16) and a second side contact (18) which are respectively connected to the first electrical circuit and the second electrical circuit;
• the actuating member is an arc-shaped structure having an opening facing the rocker, and is pivotably provided on the mounting seat;
• a first movable contact and a second movable contact are symmetrically provided on both sides of the actuating member with respect to a rotation axis of the actuating member;
• the first side contact and the second side contact are provided at the mounting seat, corresponding to the first movable contact and the second movable contact, the first side contact configured to make electrical contact with the first movable contact and the second side contact configured to make electrical contact with the second movable contact, the first electrical circuit electrically connected to the first side contact and the second electrical circuit electrically connected to the second electrical circuit;
• the rocker is rotatably provided at the mounting seat, and one end of the spring is fixedly mounted below the rocker and the other end thereof is connected to one end of the ejector rod, and
• the other end of the ejector rod abuts against the bottom of the opening of the actuating member;
• and
• a button configured to driving the rocker to rotate is provided on the housing, and the button configured to drive the actuating member to rotate in a forward direction via the rocker, the spring and the ejector rod configured to communicate the first movable contact with the first side contact to connect the light adjusting assembly to the first electrical circuit, the button configured to drive the actuating member to rotate in a reverse direction to communicate the second movable contact with the second side contact to connect the light adjusting assembly to the second electrical circuit.
