Suvalds is a set of plates (with slots) that move the bolt drive when it is opened / closed with a key. The number of plates affects the degree of secrecy of the lock.

The lock locks are reliable and resistant to mechanical breaking. The disadvantage is the corpuscular limitation in the number of plates.

The secret device of the cylinder mechanism is a teardrop block (larva) inside which there is a rotary cylinder and a group of spring-loaded pins (there may be discs or frames). Each pin is divided into two parts. The rotation of the cylinder and, accordingly, the bolt drive is possible only if the height of the pins coincides.

Cylinder locks are simple and convenient to use, but they are not resistant to burglary.
