A switch system for overhead electric extension cords for remotely controlling overhead-mounted electrical appliances, such as fans. A drop cord includes an upper end having electrical fittings connectable to an overhead power supply extension cord and the electric user cord, and the lower end of the drop cord includes a switch at an accessible level from the floor. The drop cord switch controls the circuit between the power supply and user cords, and a strain relief cable anchored overhead supports the weight of the switch.
