A method for controlling characteristics of light emitted from a surgical light includes remotely configuring a surgical light, using a remote computing system communicatively connected to the surgical light, by selecting which of a plurality of characteristics of light emitted from the surgical light are adjustable by operation of a handle assembly of the surgical light. The method includes adjusting, using the handle assembly, at least one characteristic of the plurality of characteristics of the light emitted from the surgical light according to the selection of which of the plurality of characteristics of light emitted from the surgical light are adjustable by operation of the handle assembly.

A wall station control unit includes a wall station housing and a keypad interface assembly having a keypad. The keypad interface assembly is adjustably attached to the wall station housing by a first fastener and a second fastener. The first fastener extends through a first fastener hole in the wall station housing, and the second fastener extends through a second fastener hole in the wall station housing. The first fastener and the second fastener are adjustable to change a spacing between the keypad interface assembly and the wall station housing to adjust a position of the keypad relative to the wall station housing.

Disclosed are an intelligent dimmer and a structure of an on-off assembly thereof. A first key device in the on-off assembly includes a rocker key and a movable ejector rod, one end of which is connected to an ejector rod spring and the other end of which is arranged in a groove. The movable ejector rod cooperates with a moving contact assembly including two moving contacts and two contact surfaces, the contact surfaces are connected to the corresponding moving contacts, and the moving contact assembly is connected to a circuit in a printed circuit board (PCB). The movable ejector rod is arranged between the two contact surfaces, and the rocker key is capable of driving the movable ejector rod to swing and act on the corresponding contact surface, such that the moving contact assembly swings and is connected to or disconnected from a corresponding stationary contact.

A knob-type dimmer, including a housing; a circuit board; a switch; a trigger, partially exposed to the outside of the dimmer and moves in response to external forces to trigger or release a switch to control electrical connection or disconnection because the dimmer and a power source; an electrical connection matching component; a first mounting match portion; a knob assembly, including a base, a knob, and an electrical connection component, the base including a first mounting portion which cooperates with the first mounting match portion to mount the knob assembly to the housing, where the electrical connection component cooperates with the electrical connection matching component; a second mounting match portion; a face cover, including a second mounting portion which cooperates with the second mounting match portion to mount the face cover to the housing and to at least partially cover the base.
