An electrical resistor, with two terminals, whose resistance is continuously variable by moving a knob or slider.
A rheostat that is used to vary the intensity of a domestic electric light
A switch used to select between the low and high headlamp beam on a road vehicle. (usually as "dimmer switch", primarily in North America; elsewhere "dipswitch" or "dipper switch")
A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.
