Relay Components

Your Partner for Hard-to-find Relays

A relay is a simple and very common component in electric circuits.  Relays are electromechanical switches that can be actuated by an electrical signal rather than by manually opening or closing the switch.  This small signal acts as a gatekeeper for a much larger electrical signal.  The ability to have low-power control over a high-power signal is what makes them such prominent electrical components.

Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal.  There are many different types of relays including but not limited to automotive relays, coaxial relays, contactors, electromechanical relays (EMRs), electrothermal relays (thermal relays), force-guided contact relays, general purpose relays, high frequency and RF relays, hybrid relays, industrial relays, latching relays, low signal relays, machine tool relays, mercury relays, mercury-wetted relays, multi-voltage relays, overload protection relays, polarized relays and non-polarized relays, power relays, reed relays, safety relays, signal relays, solid-state contactors, solid state relays (SSRs), static relays, time delay relays, and vacuum relays.

VRG Components can source any electronic parts that are hard to find – in short supply (allocations), end of life, or have long lead times – especially relays.  We do this by leveraging our extensive network of carefully vetted, reliable suppliers to provide you with the right components to meet your needs.

Our mission is to supply hard-to-find, high-quality electronic components to maximize our customer’s production processes.  With the ability to source components from more than 500 leading manufacturers we can secure the relays required for your project.

Relay Applications

A relay is an electromechanical switch that can be operated by an electrical signal.  This electrical signal then acts as a gatekeeper for a much larger electrical signal.  The ability to control a low power signal with a high power signal makes the relay a prominent electronic component.

There are a vast number of relay applications with criteria based on the rating of contacts, number & type of contacts, the voltage rating of contacts, operating lifetime, coil voltage & current, package, and so on.

  • Relays are frequently used in power system networks for controlling purpose, automation purpose, and protection purpose.
  • The typical applications of electromechanical relays include motor control, automotive applications such as an electrical fuel pump, industrial applications where control of high voltages and currents is intended, controlling large power loads, and so on.
  • Railway routing and signaling are controlled using relay logic and are considered a key application of relay logic.  This safety-critical application is used to reduce accidents and to avoid the selection of conflicting routes by using interlocking.
  • Large relay logic circuits are used in elevators.
  • Relay logic circuits are used in electro-hydraulics and electro-pneumatics for controlling and automation purposes.

Electromechanical Switches

An electromechanical switch uses a mechanical action to change the direction or orientation of path continuity within its terminal base.

Connectors / Interconnects Close Up on white background


An electrical connector is an electromechanical device used to join electrical conductors and create an electrical circuit. Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket.
