Up to what age can my children receive child benefits in Switzerland?

I have heard of parents in Switzerland receiving child benefits for their adult children. Is that even possible? Up till what age are children eligible for child benefits?

You can continue to receive child benefits for your children for as long as they are undergoing some form of education which involves at lest 4 classes weekly. Your child may earn a monthly salary of up to 2350 Swiss francs and still remain eligible to receive child benefits. However, child benefit entitlements end when a child turns 25 years old.
