ARIA’s 16AX Single-Pole Switch Mechanism is a workhorse of the ARIA range. Its 16AX rating is built to handle high inrush currents. 1-way and 2-way switching covers everyday circuits. Fan, Heat, Light and Sensor icons make the function clear at a glance without adding a label to the plate. The mech comes in three finishes, each for one coordinated front face. Matte White pairs tone-on-tone with Matte White ARIA plates. Matte Black pairs with Matte Black and Dark Grey Silver ARIA plates. Dark Grey pairs with Light Grey Brass ARIA plates. The 30 Series format keeps the fit familiar. Grid mounting gives every flick a crisp response without cover-plate flex, while screw terminals take up to four 1.5mm² or two 2.5mm² conductors. Tested to 50,000 mechanical cycles, more than four times the required minimum, and backed by a 25-year parts-and-labour warranty.
