Zusammenfassung:	A control cam unit is fixed to a motor crank shaft. The cam has a connecting rod to a pivot which is at the top of the spring housing and guided in a slot of the supporting frame. Consequently the cam is fixed by a pivoted connecting rod to a spring assembly which is retained between its two end supports. The motor turns the crank shaft through a certain angle to operate the switch mechanism and in doing so energy is stored by compressing the spring. The spring energy then assists switch operation in the reverse mode.
