Frequently Asked Questions

What is a relay?

A relay is a switch that is controlled by electricity. It has a set of contact terminals for operation and a set of input terminals for one or more control signals. There is no limit on the number of making contacts, break contacts or other possible contact types that can be included in a switch.

Relays control several circuits with a single signal or a circuit with a low-power signal that is not connected to any other circuits. Relays’ original application was in long-distance telegraph circuits, where they served as signal repeaters by retransmitting a signal from one circuit to another. Telephony switching systems and early computers both heavily used relays to process logical commands.

Although electromagnets are typically used to close and open relay contacts, other types of relays have been developed. Solid-state relays, for example, use semiconductor features for control rather than moving elements. Relays with calibrated operating characteristics and, in some cases, numerous operating coils are employed in modern electric power systems to accomplish the same functions traditionally done by protective relays.

A single control pulse is needed to keep the switch on permanently with a latching relay. By contrast, the controller can be reset by applying a pulse to the other control terminals or by applying a pulse with the opposite polarity, but further applications of the same pulse type have no effect. The circuits the relay controls should continue to function normally even if the power goes out; this is where magnetic latching relays shine.

You can think of a simple electromagnetic relay as a coil of wire wrapped around a soft iron core (a solenoid), an iron yoke that provides a low reluctance path for magnetic flux, a movable iron armature, and some contacts (there are two contacts in the relay pictured). One or more movable contacts are mechanically connected to the armature via a hinge at the yoke. When the relay is turned off, an air gap forms between the armature and the coils in the magnetic circuit, which is maintained by the spring holding the armature one set of contacts in the depicted relay is closed, while the other is open in this state. Depending on the intended use, some relays may have a different number of contacts than others. A similar wire connects the armature of the relay shown to the yoke. The yoke is soldered to the printed circuit board (PCB), which completes the circuit between the armature’s movable contacts and the PCB’s circuit track.

To put it simply, a switch works because of the magnetic field produced by an electric current flowing through a coil, which in turn activates the armature, which in turn moves the movable contact(s) and either completes or interrupts the circuit with the fixed reference, depending on the design. The movement opens the set of contacts and breaks the connection if the contacts were closed when the relay was de-energized and vice versa if the contacts were open. When power is cut to the coil, the armature is pushed back to its resting position by force roughly equal to the magnetic force but much smaller. Typically, a spring is used to supply this force, but gravity is also widely employed in industrial motor starters. Relays are typically built for speedy operation. Reduces noise at low voltages and prevents arcing at high voltages and currents.

What is a General-Purpose Relay?

DC relays

Relays are made to work with a DC input.

AC relays

Relays built to function with AC input.

Relays with polarity

Relays in DC adjust their status based on the polarity of the control input current.

Relay types include single-side stable, double-side stable, and centrally stable. Nonpolarized relays are unaffected by the polarity of the control input current (neutral relays).

Sealed relays

Relays that are fully enclosed and sealed in a container.

Note: Typically, sealed relays are welded or another similar means to encapsulate them in a metal and metal or metal and glass container.

Even though enclosed relays are closed without the use of welding or other forms of sealing, they are also referred to as sealed relays.

Hinged relays

The structure of the electromagnet is referred to in this categorization.

Hinged relays work by moving the armature around the fulcrum to switch directly or indirectly connections.

Note: Side armature-type hinged relays have armatures that move perpendicular to the direction of the core axis.

End-on armature type hinged relays are those with armatures that move in the axis’ direction.

Plunger Relays

This categorization describes the electromagnet structure. In a plunger relay, the armature is located in the middle of the coil and rotates around the coil axis.
