A control device for a laundry drier in which tumbling of the load articles causes them to form intermittent connections between contact electrodes. The control device is responsive to the state of dryness of the load includes means for causing an electrical current flow through a resistor, the electrodes and the load articles such that a potential difference is developed across the resistor. This potential difference is applied to a comparator for comparison with a reference potential value. A resettable timing circuit is reset to the beginning of a fixed time interval whenever the detected potential difference exceeds the reference value and the timing circuit operates an output switch only if no resetting action has occurred in that time interval.
