# Relays ## Navigation - [Back to Sitemap](https://www.flux.ai/sitemap.md) - [Back to Passive Components](https://www.flux.ai/sitemap/passive-components.md) ## Description A relay is an electrically operated switch that allows a low power circuit to control a high power circuit. It consists of a coil, which is activated by an electric current, and a set of contacts that open or close when the coil is activated. Relays have a wide range of use cases, including controlling the flow of electricity in a circuit, protecting electrical components from damage, and amplifying signals. They are commonly used in automotive systems, HVAC systems, and control panels. Flux.ai has the world's largest community-driven public library of relays, with footprints, symbols, datasheets, and simulation models. This library is a valuable resource for engineers and designers looking for reliable and accurate information on relays. ## Items (Page 1 of 221, 5522 total) - [G3MB-202P Relay Module](https://www.flux.ai/rafalozano/g3mb-202p-relay-module.md) - G3MB-202P Relay module - [DPDT Relay 24VDC](https://www.flux.ai/maxkoning/dpdt-relay-24vdc.md) - MIN RELAY, 2 PDT, 24 VDC Phoenix Contact SPDT PCB Mount Non-Latching Relay, 24V dc Coil 15.7 Phoenix Contact - [5V Relay Modular](https://www.flux.ai/jharwinbarrozo/5v-relay-modular.md) - 5V relay re-usable, modular, a sub-layout.
