Key Switch Atlo ATLO-KB-18 — Atlo key-operated electrical switch

Atlo ATLO-KB-18 is a key-operated electrical switch engineered for controlled manual operation of electrical circuits. The device uses an exchangeable key mechanism to provide tamper-resistant on/off control suitable for situations where switching must be restricted to authorized personnel. The compact design allows installation in industrial or commercial panels, machines, and control stations where reliable, intentional switching and added access control are required.

Advantages

The key-operated mechanism limits unauthorized use and reduces accidental switching by requiring a dedicated key for operation. The switch offers a straightforward on/off function with clear mechanical feedback and a robust actuator intended for frequent use. Its construction is appropriate for integration into existing control panels and safety interlock systems, providing a simple physical security layer without complex electronics.

Suitable for

• Access control for equipment and restricted areas
• Machine start/stop and emergency enable/disable circuits
• Safety interlock and authorized-operation applications
• Commercial buildings, industrial panels, and control cabinets

Key specifications

• Operation: key-actuated on/off switching
• Key system: exchangeable key mechanism for controlled access
• Mounting: panel or control cabinet mounting compatible form factor
• Actuation: mechanical rotary or push style (mechanical feedback)
• Environment: suitable for indoor industrial and commercial installations

How to use

Install the key switch into a suitably cut panel opening and wire the switch contacts according to the circuit diagram of the equipment, observing all applicable electrical safety standards and lockout/tagout procedures. Insert the key to change the switch state: turn or push the key to move between the on and off positions depending on the switch variant. Remove the key where required to lock the switch in the chosen position, preventing unauthorized operation. Test the switching operation after installation to confirm correct wiring and mechanical action.

Usage recommendations

Use the exchangeable key to control which personnel can operate the switch and store spare keys securely. Perform periodic mechanical and electrical inspections to verify contact integrity and key mechanism function. Follow local electrical codes for wiring, mounting orientation, and any required protective devices such as fuses or circuit breakers.
