A contactor, contactor switch or contactor relay is a device designed for switching an electrical circuit on or off. They are part of the relay family, but the main difference is that a contactor is used in applications with higher current capacity is involved. Contactors are typically used for motors, lighting circuits, heating, and other electrical loads. A contactor can function on its own or as a power control device or as part of a motor starter. You can find out more in our comprehensive [contactors guide](/web/content/discovery/ideas-and-advice/contactors-guide).

We also stock a [selection of accessories](https://uk.rs-online.com/web/c/automation-control-gear/contactors-auxiliary-contacts/contactor-accessories/ ) used to enhance the function of the contactor including, [Contactor Overload Relays](/web/c/automation-control-gear/contactors-auxiliary-contacts/contactor-overload-relays/), [auxiliary contacts](/web/c/automation-control-gear/contactors-auxiliary-contacts/auxiliary-contacts/), mechanical interlocks, and much more.

### How do contactors work?

Contactors, unlike standard relays, are specifically designed to connect to high current load devices. Used in larger-scale control circuit applications, a contactor is a switch that can be controlled remotely, specifically designed to switch a large amount of electrical power through its contacts. If a device can switch more than 10 amperes, it is called a contactor. These devices also feature high coil voltages which are rare within relays.

### Browse Contactors by Type

There are various types of contactors, and each type will have its own set of specifications depending on your application. Some key specifications are:- 

- AC Contactor or DC Contactor with coils including [12 V](https://uk.rs-online.com/web/c/automation-control-gear/contactors-auxiliary-contacts/contactors/?if=12v-contactors ), 24 V, 48 V, 110 V, 240 V, 400 V, and 440 V.
- Reversing or non-reversing functionality.
- AC3 and AC1 categories.
- [Single pole contactors,](https://uk.rs-online.com/web/c/automation-control-gear/contactors-auxiliary-contacts/contactors/?if=single-pole-contactors) [2 pole contactors](https://uk.rs-online.com/web/c/automation-control-gear/contactors-auxiliary-contacts/contactors/?if=2-pole-contactors), 3 poles 4 poles, and even 8 and 10 pole variants.
- [Lightening Contactors](https://uk.rs-online.com/web/c/automation-control-gear/contactors-auxiliary-contacts/contactors/?if=lighting-contactors ).
