BLASI – Key-operated switch 2xNO
BLASI – Key‑operated switch 2xNO is a rotary key selector used in BLASI control cabinets and automatic door systems to enable or change operating modes. It provides two normally open (2xNO) contacts, which close when the key is turned to the active position and open again when the key is returned or removed. This BLASI – Key‑operated switch 2xNO is built for 22 mm panel mounting and is typically rated for low‑voltage control circuits, making it suitable for enabling maintenance, service mode, or manual/automatic selection without affecting the main operation. It offers controlled access because the switch can only be operated with the correct key, improving safety and discipline on the panel.
Product Details
BLASI – Key‑operated 2xNO is a mechanical selector switch that operates via a key and is used in BLASI automatic door and barrier control panels to manage modes, permits, or service functions. The 2xNO configuration means the switch has two normally open contact paths that connect only when the key is turned to the designated ON or RUN position, allowing the system to receive a start, enable, or mode‑change signal only under authorized control. This helps prevent accidental operation and protects against untrained users tampering with the equipment.
The item is designed for standard 22 mm panel installation and typically supports common industrial control voltages and currents found in BLASI systems, with robust key‑mechanism construction that withstands repeated use. Because it is a purely mechanical contact device, it integrates easily into existing control wiring without needing extra electronics. By using the BLASI – Key‑operated 2xNO, maintenance teams can define clear access levels, isolate machines for service, and support safe, key‑controlled operation in commercial and industrial environments.
