BLASI – Key switch JUNG
BLASI – Key switch JUNG is a JUNG‑brand key‑operated switch module used in BLASI‑type automatic‑door and barrier installations, typically mounted in JUNG flush or surface‑mounted frames on operator tubes or walls. The key switch has a 1‑ or 2‑pole configuration (often 1‑pole 2‑way or 2‑pole), with screw‑type terminals for connections up to about 2.5 mm², and is rated for typical control‑circuit use (for example 16–10 A at 230–250 V AC). It is designed to fit standard JUNG LS‑ or AS‑range centre plates, so it slots neatly into BLASI‑area switch plates while offering secure, key‑controlled operation. BLASI lists this simply as “Key switch JUNG” in its sitemap, so technicians usually source a standard JUNG key‑switch insert that matches the BLASI‑panel mounting pattern and voltage level.
Product Details
BLASI – Key switch JUNG sits behind a JUNG‑brand design‑frame (1‑gang or 2‑gang) and provides a manually operated, key‑controlled way to change the mode or state of BLASI‑related equipment, such as activation circuits, emergency release paths or operator‑mode selectors. The key switch is mounted flush or semi‑flush, with the key cylinder and operating lever passing through the JUNG plate so users can turn the key while the wiring and internal contacts remain hidden and protected. Many JUNG‑type key‑switches for this application are supplied with a DIN‑18252‑style half‑cylinder and a center‑plate that can only be removed when the lock is in the unlocked position, which adds protection against dismounting and tampering. This makes BLASI – Key switch JUNG suitable for high‑traffic or security‑sensitive BLASI‑based entrances such as office lobbies, hospitals and malls.
The switch is typically wired into low‑voltage control circuits, with screw terminals that accept both rigid and flexible conductors; its compact body and 70×70 mm footprint follow JUNG‑series standards, allowing it to be dropped into JUNG LS‑ or AS‑range plates already used around BLASI‑type automatic doors. BLASI treats “Key switch JUNG” as a generic but frame‑compatible component, so contractors choose a JUNG‑supplied key switch insert (with or without protection‑against‑dismounting, depending on the version) that matches the lock‑system and key‑coding scheme on that site. By using BLASI – Key switch JUNG, facility managers and BLASI‑area technicians gain a secure, standardized way to locally control or override BLASI‑related functions, keeping the installation neat, vandal‑resistant and aligned with JUNG‑brand design.
