The Last Line of Defense in Critical Systems.
When Failure Isn't an Option, There's Detroit Switch, Inc.
Detroit Switch, Inc. manufactures pressure switches, temperature switches, and differential pressure switches used in high-stake environments — from naval vessels and locomotives to industrial and energy systems.
These aren't components you think about
when everything is working.
They're the ones that matter when something isn't.
Our switches monitor operating conditions and initiate actions such as alarms, pumps, fans, lights, and other electrically operated equipment when predetermined thresholds are reached.
These are the components systems depend on when conditions push past their limits.
Designed for Real-World Conditions
Detroit Switch designs and manufactures industrial control switches built for environments where conditions are demanding and expectations are high.
Pressure Switches
Monitor and control system pressure in environments where stability and response time matter.
Temperature Switches
Respond to changes in heat, helping maintain safe operating conditions in critical processes.
Differential Pressure Switches
Detect changes across systems and initiate the appropriate response when conditions drift.
Used in systems where:
- Equipment operates under constant stress
- Access is limited once installed
- Failure carries real consequences
Built Around Your System —
Not Just the Spec Sheet
Most switch manufacturers expect you to know exactly what you need before you reach out. That's not how Detroit Switch works. We start with the application — how your system operates, what it needs to monitor, and where things can go wrong.
No Blind Product Selection
From there, we help determine the right configuration based on real-world conditions, not assumptions. Every recommendation starts with your application.
Clear, Honest Communication
We provide clear communication about what will and won't work — no overselling, no guesswork. You'll know exactly what you're getting and why.
Solutions Around Real Behavior
Solutions designed around actual system behavior, not theoretical conditions. Because in complex systems, getting it right the first time matters.
When Systems Must Behave as Expected
Systems don't fail under ideal conditions.
They fail under pressure — when something upstream doesn't behave the way it should, or when operating limits are exceeded.
Detroit Switch builds pressure control switches, temperature control switches, and differential pressure switches for those moments.
Our products act as secondary safeguards within a system — monitoring conditions and triggering action when something moves out of range.
It's not about perfect operation.
It's about what happens when conditions aren't perfect.
Monitoring Under Stress
Our switches continuously monitor system conditions — remaining dormant until thresholds are exceeded, then triggering immediate response to protect your system.
Secondary Safeguard Layer
Positioned as a critical secondary defense, Detroit Switch products ensure that even when primary systems reach limits, escalation is prevented before damage occurs.
Designed for Harsh Realities
From naval vessels under high shock and vibration to locomotive braking systems — built for environments where ideal operating conditions simply don't exist.
Pressure, Temperature,
and Differential Pressure Switches
Pressure Switches
Control switches designed to monitor and control pressure in systems where stability and response time matter. Multiple configurations available.
Temperature Switches
Control switches that respond to changes in temperature, helping maintain safe operating conditions in critical processes and demanding environments.
Differential Pressure Switches
Differential pressure switches used to detect changes across systems and initiate the appropriate response. Supports multiple configurations and applications.
Why Choose Detroit Switch?
Detroit Switch, Inc. is a family-owned, American manufacturer with decades of experience supporting critical systems. We've built our reputation on reliability, long-term relationships, and a commitment to doing the work correctly.
Detroit Switch products are used in environments where conditions are anything but controlled.
- Naval systems operating under high shock and vibration
- Locomotive systems responsible for braking, motion control, and engine temperature controls
- Industrial and energy systems where uptime is critical
These are environments where equipment is pushed — and where failure isn't just inconvenient. It's unacceptable.
Detroit Switch products are not designed for short-term performance. They are built to operate reliably over time — often for decades.
- Multi-decade service life
- No planned obsolescence
- Designed for long lifecycle systems
In many applications, our switches remain in service long after other components have been replaced. Because the best switch is the one you don't have to think about.
Our switches are manufactured to meet strict quality and compliance requirements, including military and industrial standards. Our process emphasizes:
- Precision manufacturing
- Tight tolerances
- Consistent, repeatable performance
Because meeting a specification once isn't enough. It has to perform the same way every time.
Detroit Switch is a family-owned, American manufacturer with decades of experience supporting critical systems. We've built our reputation on:
- Reliability in demanding environments
- Long-term relationships with customers
- A commitment to doing the work correctly
Today, that same approach continues — supporting the industries we've served for generations while expanding into new applications and markets.
