Lock with electrical system - has spring pins closing contact on bearing against housing rear wall

摘要

The security lock with a system of electrical contacts has first spring-loaded security pins (6) in a housing (2), and second pins (21) moved by a key (40). Third pins (20) between the first and second ones have an axial length equal to the thickness of a disc (12) coupled to a bolt (17). When the first pins bear against the housing rear wall (8), one or more of them close an electrical contact. USE/ADVANTAGE - Lock guarantees high degree of security even when mass-produced.
