A combination electric lamp dimmer with automatic photocontrol which is adapted for mounting within a conventional electrical junction box such as mounted within walls. The devices includes a rotary dimmer switch for adjusting the current magnitude provided to the lamp to establish the magnitude of light produced thereby. The position of the dimmer switch is controlled by a manually rotatable knob. The knob includes an opening in it to allow ambient light to pass therethrough. A photocell is mounted behind the knob. When a knob is rotated to a position wherein the opening is disposed over the photocell, the photocell is enabled to monitor the ambient light. When the ambient light intensity drops below a predetermined value, the photocell and switch means responsive thereto enable current to be provided through the dimmer to the lamp to illuminate it.
