A control panel interacts with the control system and has a plurality of actuatable elements and a display area associated with each actuatable element for displaying a legend associated with the actuatable element. The control system is functionally connected to the control panel and is operative to change the legend associated with an actuatable element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching facility having a control panel with relegendable buttons","description":"A switching facility has a plurality of input ports for connection to signal sources in multiple categories, each category having multiple members, a plurality of output ports for connection to signal","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621426","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
