Name: BLASI - KDT-2 key operating switch - Best Spare Parts
SKU: BLSP-7910185

BLASI – KDT‑2 key operating switch is a compact, key‑controlled selector used on BLASI automatic doors and barriers that features two independent key positions or two‑way control logic. The BLASI – KDT‑2 key operating switch typically allows an authorized user to switch between modes such as OFF–Automatic–Continuous or up–down direction, depending on the application, with a single key unit. It is mounted on the door frame or control panel at about 1200 mm height so staff can safely stop, start or override the door’s movement. With a robust cylinder and sealed housing, BLASI – KDT‑2 key operating switch is suitable for indoor and outdoor BLASI‑based entrances where secure, dual‑mode manual control is required.

Product Details

BLASI – KDT‑2 key operating switch integrates into the safety and control logic of BLASI revolving, swing and sliding‑door systems to provide a single, dual‑function key‑operated interface. The “2 key” design usually means either two distinct mode positions (such as two stages of manual control or reset options) or a two‑way directional selector that can reverse the running direction of the door when turned. In both cases, the BLASI – KDT‑2 key operating switch sends clear ON/OFF or change‑state signals to the BLASI control unit, allowing cleaning crews, security staff or technicians to stop the door, force continuous motion or temporarily switch to a special operating mode without entering the panel. This compact, key‑only access reduces the risk of unauthorized tampering while still supporting flexible manual intervention.

Engineered for repeated use in commercial environments, BLASI – KDT‑2 key operating switch features a durable key lock and reliable internal contacts with standard screw terminals for easy wiring. Its compact body can be mounted flush or surface‑mounted on the wall, pillar or operator housing, giving a neat, low‑profile interface at a convenient height. The housing is typically rated for splash‑resistance or basic environmental protection, which suits BLASI installations in malls, airports and office buildings. By using BLASI – KDT‑2 key operating switch, facility managers and technicians gain a secure, code‑ready control point that supports safe dual‑mode operation, simple override behaviour and consistent performance in BLASI‑based automatic‑door and barrier systems.
