What is Electrical Mechanical Assembly?

Through the combination of electrical circuitry with some mechanical parts, all these elements help in playing a significant role in electronic and electrical systems across different industries. These include power generation, military, communications, aerospace, etc.

Furthermore, electromechanical assemblies range from the simple assemblies to the complex ones. All has to be constructed and designed with care. This is to make sure that they have great manufacturability and functionality. For the purpose of this topic, we will be focusing on what electromechanical assembly is, the different types, as well as the applications and industries that they are useful for.

Explaining what Electromechanical Assemblies Are

Electromechanical assembly deals with everything involving cable and wire subassemblies to the complete system assemblies called box builds. Furthermore, in all these, the mechanical and electrical components, as well as subassemblies function as one unit in offering a specific mechanical operation. Also, the subassemblies and components that are integrated in a specific electromechanical assembly usually vary. This depends on the part where you’ll be installing it, as well as the application you’ll be using it for.

This could include wire and cable assemblies, power supplies, DIN rails, switches, sensors, PCBs (printed circuit boards), safety mechanisms, and programmable logic controllers. Also, during the process of assembly, skilled specialists in electromechanical assembly follow specific blueprints for the integration of electrical circuitry with these mechanical elements.

Furthermore, there is a need for these specialists to be highly skilled in some electrical system fabrication aspects. These include techniques for surface mounting, schemes for through hole mounting, circuit layout, and soldering. Asides from requiring a good understanding of all the mechanical components used, the entire assembly process deals with handling of both delicate and small mechanical components using great coordination, precision, and focus.

What are the Types of Electromechanical Assembly?

Generally, the designing and building of the electromechanical assemblies are to help in performing an operation. Let us consider some of the commonly manufactured types.

Sensor and Switch Assemblies

The two main elements of the electronic system are sensor assemblies and switch assemblies that differ in the functions that they offer, as well as the components that are used for their construction. Typically, the switch assemblies are used in connecting or disconnecting the power supply that gets to the electrical component. Also, the sensor assemblies, on the other hand, are designed for converting stimuli like sound, motion, light, or heat to electrical signals. Generally, the switch assemblies are made up of these components.

  • Wiring harness: This helps in holding the switches into place and offers a site for the electricity to pass through or leave the body of the switch.
  • Contacts: This controls electrical current flow into the switch
  • Switching mechanism: This is a push button or toggle device that helps in controlling the device’s operation.

The sensor assemblies include:

  • Connection heads: that allows the connection of the transmitter and the sensor wires
  • Sensing elements: This detects physical properties like radiation, pressure, temperature, etc
  • Transmitters: This helps in transmitting gathered data regarding the targeted property
  • Housings: useful for the protection of the sensing elements

Panel Assemblies

There are some electromechanical assemblies that are placed into panels. Typically, they serve as a method by which users can control electrical power distribution to the connected circuits. Also, all the processes involved in the creation of the assemblies could involve:

  • Panel wiring
  • Holes drilling for mounting the hardware
  • Sawing or punching holes for the components
  • Positioning each of the components on the right location

DIN Rail Assemblies

The DIN rails, which are also called mounting rails, are useful in mounting other components in a specific electro mechanical assembly. Also, you have to configure them in line with the subassemblies and components.

Power Supply Assemblies

Power supply offers electrical power to one electric load. This is possible through the conversion of current to the right format, as well as the voltage needed to power it. In addition, power supplies could be designed as standalone devices, or they can be integrated into appliances. Also, the general components of any power supply assembly are highlighted below.

  • Regulator: This reduces ripple voltages that the filter leaves behind
  • Filter: It helps in smoothing the waves present in the DC output out after rectification
  • Rectifier: This converts the incoming power from an AC source to DC
  • Transformer: It modifies the incoming voltage
  • Housing: Protects all the remaining components

Transformer Assemblies

These assemblies help in transferring electrical energy in-between electrical circuits (at least two). Also, they function by decreasing or increasing the level of voltage in line with the application’s requirements. Furthermore, the assemblies include insulating materials, secondary and primary winding, laminated core, and application-specific accessories and tanks.

Harness and Cable Assemblies

These are made of wires or cables, which transmits electrical signals or power. These components include

  • Connectors: These are useful in connecting wires and cables to each other as well as to the electromechanical devices.
  • Cables and wires: Helps in carrying the signals or power
  • Fuses: This prevents any damage that has been caused due to power surges
  • Ties: This ensures the wire harnesses stays fixed to the system or device.

Applications of Electromechanical Assemblies

There are some industries, which rely on an electromechanical assembly for their proper functioning.


The electrochemical assembly used in today’s automotive industry is well designed to offer a long life of operation and high reliability while offering the design flexibility required to meet the different automotive system requirements.


This industry works with high-precision, compact, and reliable electrochemical assembly having layouts that are custom designed in accommodating the features of different aircraft systems.


Agricultural equipment like combines, sprayers, and tractors, relies on sensors, switches, and an electromechanical assembly which operates efficiently and effectively.

Other applications include fire protection, military, computer interfaces, printed circuit boards, assembly line, electronic parts, hand tools, and heavy equipment.
