PURPOSE: To operate a ventilating device in accordance with various operating modes without depending on the type of the ventilating device. CONSTITUTION: This ventilating switch device is provided with first to third timer parts 1 to 3. When an intermittent ventilation switch 6 is turned on, the first timer part 1 and the second timer part 2 alternately perform a timer operation and a control part 5 controls a load drive part 4 during the timer operation of the first timer part 1 to operate a ventilating device FL. 7 Further, only during the timer operation of the second timer part 2, the operation of the ventilating device FL is stopped. While a sequence of these operations are repeated, the ventilating device is operated in accordance with an intermittent ventilation mode. When a forced ventilation switch 7 is turned on, the control part 5 controls the load drive part 4 only during the timer operation of the third timer part 3 to operate the ventilating device FL based on a forced ventilation mode. After the forced ventilation mode is finished, an automatic ventilation mode is realized. When a stop switch 8 is turned on, the ventilating device FL can be stopped under any operating mode. |
