Abstract
A child safety door latch system includes interchangeable pushbutton compression springs of varying tensions proportional to selected values of thumb opposition strength. A pair is selected for a predetermined age group. A pair of handles each contain one of the selected pair of compression springs and a pushbutton. A latch includes a latch compression spring and a latch slider. A master connector is coupled to the latch slider. In a locked mode, the selected pair of compression springs cooperate with the latch compression spring such that the latch protrudes from the latch sleeve, holding the door locked.
