Configurable Switch Panels for Heavy Equipment

Designing Around Cab Space, Machine Functions, and Lighting

 

A heavy equipment cab has limited space—and a growing list of functions operators need to control. For OEM engineers, the challenge is not simply finding room for more switches. It is determining how the switch panel’s layout, functionality, and lighting should work together within the machine’s design.

Configurable switch panels give engineers more options for addressing those requirements. GS Global Resources works with OEMs to evaluate available mounting space, understand machine operating modes, and develop panel configurations that fit the application. That process can include compact layouts, offset button arrangements, mode-dependent functions, and configurable lighting.

Designing Switch Panels Around Limited Cab Space

Space is often one of the first constraints engineers encounter when developing or updating a cab’s controls.

“Probably the biggest challenge that we run into is space constraints,” says Josh Heinz, GS Global Resources’ Vice President of Engineering.

Individual rocker switches may meet the functional requirements, but their combined footprint can exceed the space available on the dash or console. Configurable switch panels create additional layout possibilities, allowing engineers to consider different button positions and housing shapes rather than relying on a conventional switch arrangement.

GS Global Resources has developed panels with offset buttons that form approximately triangular or trapezoidal patterns. Different housings also allow panels to fit various locations within the cab, including spaces that would not accommodate a typical rocker-switch arrangement. The goal is to evaluate the panel’s physical design alongside the available mounting area—not treat its dimensions and shape as fixed requirements that the cab must accommodate.

Why the Function List Does Not Always Determine the Button Count

A machine specification may include 15 or 20 digital input/output points. However, that does not necessarily mean the operator needs a separate physical button for every function.

“We have to really understand when each one of those are going to be used,” Heinz explains.

Before determining the panel’s size and layout, the controls team needs to understand how the equipment operates:

• Does the machine have distinct operating modes?

• Which functions are active in each mode?

• Which functions must be available simultaneously?

• Could a switch location support different functions in different modes?

A machine might use one group of functions in plow mode and another during travel. Understanding those operating conditions helps engineers evaluate whether certain functions can share a button location rather than requiring dedicated switches.

Using Mode-Dependent Switch Functions

Where the application allows it, a switch location can perform different functions depending on the machine’s active mode. A generic symbol or icon can identify the button while its assigned function changes with the operating mode.

This makes the machine’s operating sequence an important input to panel design. Engineers need to understand not only what functions the equipment performs, but also when the operator needs access to them.

Evaluating those requirements before finalizing the layout can reveal opportunities to combine switch locations and fit the necessary controls into the available space.

Expanding Lighting Options With RGB Switch Panels

Lighting is another part of configuring a switch panel around an OEM’s requirements.

GS Global Resources has developed an RGB switch-panel design to expand the available color options beyond the discrete LED colors used in its established panels. The design is intended to provide standard colors and customer-specified options, including colors selected to complement the cab interior.

“If that customer has a general color that they want to see the interior of the cab, we can change those switch panels over to make that look,” Heinz says.

Lighting requirements can also be considered alongside the machine’s functions and operating modes. Defining the desired colors and lighting behavior early gives the engineering team a clearer specification for the panel.

For an OEM developing a new cab, that means lighting belongs in the initial control-layout discussion rather than being treated solely as a finishing detail.

What OEMs Should Define Before Selecting a Switch Panel

A useful switch-panel specification starts with more than a button count. To establish how the panel should fit and function, OEMs should be prepared to discuss:

• Available mounting space and the proposed location within the cab.

• Functions the operator needs to activate or control.

• Machine operating modes and the functions used in each.

• Functions that must remain available simultaneously.

• Preferred button arrangements and icon requirements.

• Desired lighting colors and behavior.

• Panel-addressing requirements.

These details connect the panel’s physical configuration to the machine’s operating requirements and provide a starting point for evaluating the design.

Develop a Switch Panel Around Your Application

A configurable switch panel is more than a way to fit additional buttons into a smaller area. It brings together decisions about mounting space, machine functions, operating modes, lighting, and electronics.

By evaluating those requirements together, GS Global Resources helps OEMs develop switch-panel configurations around the needs of their equipment rather than treating the panel as an isolated component.
