Claims

[Scope of utility model registration request]

A relay device consisting of a main switch connected to W, a relay coil whose energization from the power supply is controlled by turning on and off the main switch, and a relay switch which turns on and off by turning on and off the relay coil, and a relay switch of the relay switch. A load control device including a load whose energization is controlled by turning on and off, a first transistor that turns on and off as the main switch turns on and off, and the first transistor;
a second transistor that is turned off when the transistor is on and turned on when it is off; a charging/discharging capacitor that is connected in parallel with the second transistor and is discharged when the second transistor is on and charged when the second transistor is off; and charging of the charging/discharging capacitor. A chattering prevention circuit for a load-side control device, comprising: a switching element that outputs a trigger when the trigger continues for a predetermined time; and a three-terminal switching element that is made conductive by the trigger and energizes the relay coil.
