An electric air valve linkage switch for kitchen range hood ventilation. It integrates the range hood power socket, a test button and the damper connection terminal in one unit. Pressing the button opens the damper and switches on the hood; when the hood stops, the damper closes automatically after a 5-minute delay to clear residual cooking odours.
