Actuating device and key.

摘要

An actuating device (12) has a cartridge (20) within a fixed casing (16). A card-like key (14) has a key formation (84, 86. 88) which, during insertion of the key into the cartridge, displaces a finger formation (42) connected to an interference formation (44), which is then aligned with a gate (52) of a gate member (28) fixed to the casing. The gate allows passage to the interference formation allowing the cartridge to be displaced in unison with the key. An actuating formation (62) on the cartridge is provided to actuate a lock or similar device.
