Keyed Switch Box with Green/Yellow/White Illuminated Indicators

Circa Late 1990's to Early 2000's

An industrial control station consisting of a four-position control box configured with three illuminated indicator lights and a single key-operated selector switch.

Use Cases:

The specific combination of components is commonly found in a variety of industrial and commercial settings:

• Machine Operation & Access Control: The key switch acts as a safety or security feature, allowing only authorized personnel to enable or disable the machine, switch between manual/automatic modes, or perform maintenance. The lights provide immediate visual feedback on the machine's status.

• Building Automation Systems: The control station might be used to manually override or select operational modes for systems like HVAC or security, with the key switch ensuring only specific maintenance staff can change settings.

• Process Control: The control box can be used in the manufacturing industry to control a specific stage of production. For example:

• The green light indicates the system is running or in a "ready" state.

• The yellow/amber light signals a warning, caution, or a standby/intermediate state, alerting an operator to check for potential issues.

• The white light often signifies a general status, a user command has been accepted, or simply that power is on.

• Material Handling and Small Lifting Systems: The unit could serve as a local control for hoists or conveyors, where the key is necessary to initiate or change the direction of movement.

• Explosion-Proof or High-Security Environments: In hazardous locations, specialized versions of these boxes are used to ensure secure and safe operation of equipment, preventing unauthorized access that could cause a safety incident.

Functional Breakdown:

• Illuminated Indicators: These lights use color coding to help operators quickly interpret machine states, reducing human error.

• Key-Operated Switch: This switch enhances safety and operational security by preventing unauthorized individuals from controlling the machinery.

NOTE:

• 2-Units available.

• LED indicators can be rigged to illuminate when key is turned (via internal battery)—at client request.

• Key-switch can be changeout to another type—at client request.
