Impact Switches

Crush Switches For Military, Aerospace, And Other Applications Direct From An Expert Impact Switch Manufacturer

Crush and impact switches are used to sense impact of a device and are frequently found in equipment that must be triggered or armed on impact. A common example of this is a military crush switch, which arms or triggers detonation on a warhead once it hits a surface. 

Impact switches or crush switches work by sensing an impact, shock, or abrupt force. In a crush switch, the can collapses upon impact latching the circuit closed. The crushing of the switch closes a contact that will then trigger a mechanism, whether that is a delay followed by a detonation or an automatic response.

Impact switches can be made to respond to forces detected along specific sensory axes. The range in which these forces are detected will vary based on the type of switch. Crush switches respond to triggers in a single direction.

For A Reliable Response In Mil-Spec, Aerospace, And Other Settings

Impact switches and crush switches are frequently used in mil-spec applications, but they are also vital for other industrial purposes. They may be used in aircraft as aerospace impact switches and are sometimes identified as delta velocity switches.

These switches are capable of sensing and responding to crash events. As an abrupt force is detected a trigger for an emergency response signal, automatic shutoff of cockpit recording, or other automated action. 

Aerospace impact and crush switches can also be used to trigger safety equipment, including airbags and other devices. They’re quite versatile and can be specially designed to perform many different functions in response to sudden force.

Industrial crush and impact switches may be installed in equipment like warehouse and construction vehicles, as well as other heavy machinery, for purposes of detecting collisions, crashes, or major upset. A data transmission can be set to signal an emergency alert or other automated response.

Why Choose Select Controls As Your Impact Switch Manufacturer?

Select Controls has vast experience in designing, manufacturing, and improving impact and crush switches for numerous uses. We have created and enhanced various designs that include standard, modified, and custom options.

We primarily work with contractors, developers, and manufacturers who serve the Department of Defense and who build equipment for various mil-spec applications. L3 Technologies, Lockheed Martin, Orion, Motorola are just a few of the companies that have relied on us. 

We work directly with engineers to identify the performance parameters of an impact switch and can suggest, modify, or create sensory components in accordance with those needs.

If you need an impact or crush switch designed to the specifics of a unique application, let us know about the end goals of your project or program and how you’d like it to function once a specific impact duration, velocity, or other force is reached.

As an experienced impact and crush switch manufacturer, we can design precision switches that are tailored to respond as you require and perform with the utmost reliability. Our testing is rigorous and includes test runs comprised of millions of cycles.

All of the materials we use in our switches meet and exceed mil-spec requirements. These factors, combined with our expert engineering capabilities, amount to switches that provide unbeatable integrity and durability.  

If you’ve had an impact or crush switch developed by another provider and it isn’t performing as it should, we can evaluate, correct, and improve on that existing design. Our team will use their experience and expertise to help ensure you gain optimal results. We can also offer exact replacements of existing impact or crush switches with identical specifications.

We know you’re looking for solutions in a tight timeframe, which is why we do what it takes to make the specification and quoting process as efficient as possible, while also accounting for your individual specs. 

We understand your primary concerns in choosing a switch manufacturer are based on your budget, required delivery time, and the resulting quality and value you’ll get for the amount you pay.
