Introducing our exciting DIY STEM Kit - the Combination Lock Box! Delve into the world of mechanical puzzles and learn how a combination lock works with this engaging educational toy. From understanding the numerical patterns to deciphering the secret code, this hands-on experience will encourage critical thinking and enhance their STEM knowledge. Unlock endless fun and learning possibilities with our STEM Kit - the Combination Lock Box!
The combination lock is one opened not by a key but by the alignment of its interior parts in a definite position. The most common types have an internal mechanism consisting of a series of three or four interconnected rings or discs that are attached to and turned by a central shaft. Manually rotating the outside knob or dial turns the discs, each of which is "programmed" to stop at a notched opening or gate.
