Seco Larm ss-090-2h0 Key Lock Switch Tubular

Product Description

The SECO LARM ss-090-2h0 is a tubular key lock switch designed to control on/off access to equipment, machinery, and security systems. It requires a physical key to operate, restricting activation to authorized personnel only. The switch uses a patented See-Saw contact mechanism that automatically self-adjusts to maintain reliable electrical contact even after extended use or contact wear. This self-adjusting design also compensates for contact misalignment caused by vibration, making the switch suitable for both stationary and mobile installations.

This key lock switch is suited for residential, commercial, industrial, and vehicle burglar alarm systems. It also fits applications in computer systems and data processing equipment where controlled, authorized access is required. Security integrators, alarm technicians, and electricians typically install this switch as part of a broader access control or equipment protection circuit.

Key Features

• Tubular key operation limits activation to authorized users only
• Patented See-Saw contact design provides automatic self-adjustment for consistent contact closure
• Maintains reliable contact even after prolonged wear or vibration-induced misalignment
• Suitable for stationary and mobile vehicle installations where road vibration is a factor
• Applicable across residential, commercial, industrial, and vehicle security systems

Compatibility

Designed as an OEM-style replacement or direct-fit component for burglar alarm systems, computer systems, data processing equipment, and general machinery requiring key-controlled on/off switching.

Installation Notes

Installation is typically performed by a licensed alarm technician or electrician. Power down the circuit and discharge any capacitive loads before wiring the switch into the control loop. Follow applicable NEC guidelines for low-voltage control wiring. Do not force the key or overtighten the mounting hardware, as tubular lock mechanisms can be damaged by excessive torque.
