The MGB offers that little bit more: it is more than a safety switch, more than a bolt, and offers a lot more functionality! Even the basic system comprising handle module and evaluation module (as interlocking module or locking module) includes numerous functions. Whether interlocking, guard locking, escape release or other functions such as pushbuttons for start/stop, emergency stop, etc. – the MGB meets all your requirements for safety-related applications.
