BLASI – Linear control switch without reset

Name: BLASI - Linear control switch without reset - Best Spare Parts
SKU: BLSP-7910078

BLASI – Linear control switch without reset is a dedicated key‑type selector used on BLASI linear sliding‑door systems to set the operating mode of the door without a separate reset position. The BLASI – Linear control switch without reset typically offers positions such as OFF–Automatic–Continuous–Hand, letting authorized users safely stop, start or override the linear door with a key. It is mounted flush or semi‑flush in the operator tube or wall, at about 1200 mm height, to match BLASI safety standards and avoid accidental operation. Because it has “without reset,” the switch does not include a special reset contact; instead, the door returns to normal operation when the key is turned back to Automatic. With simple screw‑terminal wiring it fits into the BLASI control‑circuit scheme for indoor or sheltered entrances.

Product Details

BLASI – Linear control switch without reset serves as the main key‑operated control point for BLASI‑type linear sliding‑door operators, allowing maintenance staff and security personnel to change how the door behaves. Turning the key through OFF, Automatic, Continuous and Hand positions updates the BLASI control unit so the door can be safely stopped for cleaning, run in normal sensor‑mode, forced into continuous motion for moving bulky items, or placed in manual mode for testing and adjustment. The “without reset” designation means the switch does not incorporate a dedicated reset contact; after service the operator simply returns to Automatic when the key is turned back, simplifying the interface and avoiding extra wiring steps. This design aligns with BLASI’s approach of keeping the operator‑tube layout clean and standardized for linear‑door installations.

Engineered for repeated use in commercial environments, BLASI – Linear control switch without reset uses a robust key cylinder and stable internal contacts with clearly marked screw terminals for easy integration into the BLASI safety and control wiring. The compact body can be mounted flush or on a small bracket so the front sits nearly level with the BLASI operator tube or wall, reducing the risk of impact or tampering while giving a neat appearance. It is typically used indoors or in weather‑protected locations, such as malls, hospitals and office lobbies, where secure but straightforward manual control is needed. By using BLASI – Linear control switch without reset, technicians maintain a safe, code‑compliant operating‑mode control that supports efficient service and consistent BLASI‑based linear sliding‑door operation.
