Cable pull switch is solid-state

Guardmaster Lifeline 5 has a microcontroller inside to compensate for thermal expansion and cable sag. "Because Lifeline 5 cable pull switches are solid-state switches, traditional switches typically do not cause mechanical wear," said product manager Steve Tambeau. "This means longer duty cycles can increase uptime and provide more reliable safety features." LED indicators are provided to help tighten the cable and display switch status and diagnostic information during operation. It is available in die-cast aluminum or stainless steel housings with IP66 or IP67 environmental protection respectively . Die-cast aluminum models also offer optional integrated buttons.
