Special attention has to be paid to the interaction between man and machine. Fault sources and system disturbances must be signaled reliably – and as early as possible. And if things do get critical – the top priority is to safely and quickly stop machines and bring systems offline. Our extensive range of 3SB5 commanding and Signalling devices is designed to meet the challenge. Push button actuators, selector actuators, key actuators, compact & modular indicators… our 3SB5 pilot devices let you handle every situation confidently.
