Switch Manufacturing For All Industries


Disturbance switches are components that are used as motion sensors or motion detection devices. They work by sensing vibration or movement across a specific sensory range and triggering a response. 

One of the most common functions of these switches are as vibration or tamper detectors. They can be used in a range of industrial applications as security and safe-handling assurance systems. They are also used in many aerospace and defense applications to monitor vibration levels and to indicate if a device has been moved or disrupted in any way.

The detection range and sensitivity of a switch can be adjusted to satisfy many different operational requirements, although the services of a motion sensor switch manufacturer may be required. As a standard, most disturbance and vibration switches are normally open, which means the circuit is closed only when the switch is triggered. They are also non-latching. This means that the switch will no longer trigger a response once the force is removed or stops. 

Disturbance switches can be unidirectional, meaning they sense along a single direction in a similar manner to a tilt switch. They can be planar, meaning they will detect vibration or disturbances along a horizon or plane. They can also be omnidirectional, capable of sensing disruptions across all directions. Omnidirectional disturbance switches are used when the broadest range of motion detection is required. 

As disturbance switches are used in many critical applications and as part of systems frequently exposed to the elements, it is necessary to manufacture them from materials that offer high-conductivity, as well as moisture and corrosion resistance. Mil-spec and aerospace disturbance switches will require especially rugged and enduring materials. Gold plating may be used on the switch’s contacts and tough materials like nickel are sometimes used as the housing material. 

Motion detection switches are available as standard, off-the-shelf products for use in many different commercial and industrial systems. If custom disturbance switches are required or if a switch must be suited to a highly specific placement or function, sourcing directly from a switch manufacturer will provide more options. 

What do disturbance switches do?

Disturbance switches are used to sense movement, vibration, and other disturbances. Once the switch is subjected to such a force, a circuit will close and response will be triggered. That response can include the recording of data as part of a safe-handling or tamper monitoring system, an excessive vibration alert, or the arm or disarming of a munitions device. Disturbance switches may respond to disruptions in a single direction, across a plane or horizon, or in any direction within a surrounding area. This and other sensory specifics can be determined based on how the switch is configured.    

What is a motion sensor switch used for?

Motion sensor switches are used to sense motion, vibration, and other indications of tampering or disruption within a system. Once triggered, the switch’s circuit is closed and various responses can be activated. Motion sensor switches are used in various applications, including commercial, industrial, aerospace, and defense systems. They can be used to keep track of mishandling, tampering, and excessive vibration. They can also be part of safe-arming and detonation systems in various military munitions and arms.   

What is an anti-handling device?

An anti-handling device is a munitions attachment that is used on mines, air-dropped bombs, and other remote detonation weapons. They are used to prevent tampering in an attempt to prevent munitions from being disarmed and reused by an enemy. Anti-handling devices may use disturbance switches as a primary component within such a system.
