An end to key chaos

Machinery must be protected against unauthorized access. But there are alternatives to conventional, mechanical switches.

Fewer keys and less wiring effort thanks to SIRIUS ACT ID key-operated switches

Electronic instead of mechanical locks

Especially in large plants, it is important that certain machine functions are only used by specialized personnel. For this reason, access to the corresponding operator controls is often only possible if the key is inserted. However, if this issue of changing authorizations is solved using conventional keyswitches, a separate lock has to be fitted and wired for each function. This results in considerable wiring outlay and a confusing bunch of keys for the operators of different machines.

If SIRIUS ACT ID key-operated switches are used instead, a single lock is often sufficient for a wide range of different functions and only one ID key is required to operate multiple machines.

The electronic ID key-operated switches from the SIRIUS ACT range of commanding and signaling devices has proven its high flexibility compared to conventional solutions.

High level of security and usability: authorization management with SIRIUS ACT ID key-operated switches

SIRIUS ACT ID key-operated switches can be configured so that authorization levels for machine access can be set individually. The associated keys contain an RFID chip that makes them uniquely identifiable. Key and switch are linked by a stable radio connection. The unique ID number can also be used to activate a key for several locks.


Even if the ID key is lost, the systems remain secure because the key can easily be disabled and then replaced. In addition, the use of each key is logged so that it is clear who has used which machine and when. This offers an additional security layer and enables the evaluation of information on operation, downtimes or maintenance work, which can be recorded in a database.

The following versions of the SIRIUS ACT ID key-operated switches can be used:
