Built on Trust: How Our Quality Control Systems Help Power America’s #1 Hardest-Working Machines

What We Build: Control Systems for Heavy Equipment and High-Stakes Industries

At the heart of our business, we build rugged, sealed control systems and components that can withstand the harshest conditions – from raging fires to challenging agricultural fields. Our products are designed to survive and thrive, just like the industries we serve.

Solving Real Problems with Smart Control System Design

Our control systems for heavy equipment are engineered to solve real-world challenges in the field — from leaky switches to full system redesigns. One of our recent projects perfectly encapsulates our problem-solving approach. A customer was struggling with leaking switches and lids. We stepped in and provided a solution that not only fixed the issue but also enhanced the overall functionality of their system.

One Partner from Design to Delivery

What sets us apart is our commitment to doing everything in-house — from board design and manufacturing to wire harness integration and testing — simplifying the process for manufacturers who need rugged control systems for agriculture, forestry, and emergency equipment.

Why Customers Keep Coming Back to InSource

When it comes to control systems for heavy equipment, our customers aren’t just buying a product — they’re investing in a long-term partner. Our customers keep coming back to us, and we believe it’s because of our personal relationships, expertise, and commitment to quality. We’re flexible and always ready to accommodate our customers’ priorities. Below are a few examples of what our current customers are saying:

“I have worked with InSource over the past five years on several products. My experience with them has been a positive one, as I have found them to be very easy to work with. They have proven to be accommodating and collaborative in the face of supply chain shortages, re-design efforts, and potentially challenging assembly matters. I recommend them–not just because they have shown they can deliver quality products at a competitive price, but also because they are communicative and transparent.” – J Johnson

“I have been working with Insource for about 4 years now. I very much appreciate the on time delivery and flexibility in moving my schedules in and out as needed. As a buyer I am not super technical, and their team works directly with my engineers to help design the most cost efficient/effective products to help us outfit Fire trucks.” – D Denson

“Here at Simma Software, Inc we have used Insource to manufacture PCBs for our vehicle adapters for almost 15 years. From the customer service, to meeting project deadlines, Insource exceeds our expectations consistently. I strongly recommend them to any business that is looking for a reliable partner.” – P Browne

“They have been a great customer and supplier for 15 years. Everybody I’ve dealt with is awesome. Just the best.” – JR Simma

Built to Withstand. Designed to Serve.

Our manufacturing engineers play a crucial role in launching the products we build, ensuring documentation is in place, building testers, and improving the building process. Seeing our products, like the 360 Yield Center Rain product, out in the real world is a rewarding experience that reminds us of the impact of our work.

A day in the life of our team involves solving immediate problems on the line, designing testers, and communicating with customer engineers. We believe that there’s always room for improvement in technology, and we’re constantly striving to make our systems work better.

Our dream project? More rugged modules. We excel in manufacturing these, and we’re always excited to take on more.
