BLASI – Key operated selector switch

The BLASI – Key operated selector switch controls operational modes including automatic, maintenance, and emergency release positions within FlipFlow 2 control cabinets, restricting unauthorized access while enabling rapid technician response during service calls across two-wing security, three-wing standard, and four-wing high-capacity BLASI revolving door configurations serving global hospitality and retail facilities. The heavy-duty 22mm metal bezel with chrome-plated key cylinder withstands constant personnel contact and cleaning chemical exposure while three-position 90° detent mechanism provides positive feedback for AUTO-SERVICE-EMERGENCY settings.

Matching BLASI master key system across multi-door facilities, the BLASI Key operated selector switch uses Ronis or equivalent cylinder with removal only in AUTO position preventing accidental maintenance mode activation during normal operation. Twin-pole silver contacts rated 6A/24VDC drive FlipFlow mode relays and indicator circuits while slow-break mechanism prevents contact bounce and arcing common in vibration-intensive control cabinet environments.

IP65 sealing prevents dust ingress within enclosures while laser-etched position legends remain legible through years of service across Dubai’s harsh climate conditions. The BLASI Key operated selector switch mounts to factory panel cutouts using captive stainless screws while color-coded wiring diagram on reverse eliminates installation errors. Technicians value standardized key coding across BLASI installations worldwide, exact 2NO/2NC contact compatibility with all FlipFlow firmware revisions, and proven >100,000 operation MTBF ensuring uninterrupted safety and service access compliance.
