Why Choose the Lovato KBNXL11 Key-Operated Safety Switch?
The Lovato KBNXL11 is a key-operated safety position switch with 1NO + 1NC slow-action contacts, designed for monitoring movable guards, doors and access points on industrial machinery. The switch is supplied without an actuator key, allowing the appropriate separate actuator to be selected to suit the installation.
Its slow-action switching mechanism provides defined contact operation as the actuator key enters or leaves the switch head. The KBNXL11 incorporates 1 normally open and 1 normally closed contact and features forced opening, making it suitable for safety-related machine guarding applications when correctly integrated into the machine safety circuit.
A compact 30 mm wide plastic housing helps simplify installation where mounting space is limited, while IP65 protection supports use in demanding industrial environments. With an operating temperature range of -25 to +70 °C, the KBNXL11 provides a practical electromechanical solution for guard position monitoring across machinery and automated production equipment.

Reliable Guard Position Monitoring for Industrial Machinery
Key-operated position switches are commonly used to monitor movable machine guards, doors and covers. When the separate actuator key is inserted into the Lovato KBNXL11, the internal contacts change state according to the switch mechanism. Opening the guard withdraws the actuator and changes the contact state, allowing the associated safety or control system to detect that the guard is no longer in its monitored position.
The 1NO + 1NC slow-action contact arrangement provides complementary electrical signals, while the forced-opening mechanism provides positive operation of the normally closed contact. The KBNXL11 is supplied without a key, enabling machine builders to select the appropriate compatible actuator configuration for the mechanical requirements of the guard.
Typical Applications
- Machine guard position monitoring.
- Industrial access doors and protective covers.
- Packaging and processing machinery.
- Automated production and assembly equipment.
- Conveyor and material handling systems.
- OEM machinery requiring key-operated safety position detection.
