PROBLEM TO BE SOLVED: To provide a timer switch capable of performing the easy visual check of the setting state of a present time and an operation mode. SOLUTION: A triac 1 for turning on/off power supply to a load and a control circuit 2 for turning on/off the triac 1 according to a switch input from a push-button switch and the setting of timer control are accommodated in an instrument 10. A light-emitting diode LD the lighting state of which is controlled by the control circuit 2 is provided on a front face of the instrument 10 to be viewable from the outside. The control circuit 2 is further equipped with a delay timer 2b for limiting a delay time to delay the suspension of power supply to the load when turned off. The control circuit 2 flashes the light-emitting diode LD at a predetermined cycle while the delay timer 2b limits a time and also flashes the diode LD at a cycle shorter than a predetermined cycle when the present time is not set on a clock timer 2a.
