ABSTRACT:
In order to obtain very long operating autonomy without maintenance, with low power consumption and low wear and tear, both the energizing and de-energizing of a DC motor are controlled by an electronic switching circuit providing bounce-free switching. A switching-on control circuit actuates the switching circuit, causing it to energize the motor. A switching-off control device, comprising a rotary component connected to the motor shaft and including contact elements responsive to the position of the rotary component, actuates the switching circuit to cut off the power supply to the motor after the rotary component has rotated through a predetermined angle. The arrangement is advantageous for driving apparatus which is not easily accessible and lacks reliable mains power. Another useful particularity consists in a multiple plug device whereby the rate of intermittent driving may be varied within the range of 1 day to 31 days.
