PROBLEM TO BE SOLVED: To provide a load control circuit capable of improving operability in setting a light dimming level in spite of reducing the number of components and assembly manhours in manufacturing an electronic switch. SOLUTION: A switch parent unit 10 is provided with a microcomputer 12 integrally controlling the switch parent unit 10, and a normally-opened operation switch 14. The microcomputer 12 detects a push operation of the operation switch 14 in response to a signal input to an input port Pi3, determines that the push operation of the operation switch 14 is a short one when an L-level signal is input to the input port Pi3 for a predetermined period or less, and determines the push operation of the operation switch 14 is a long one when the L-level signal is input to the input port Pi3 for the predetermined period or more. The microcomputer 12 controls power supply to a load 2 in response to the short push operation of the operation switch 14, and executes light control setting which sets the light control level of the load 2 in response to the long push operation of the operation switch 14.
