relais

Relais is a term of French origin meaning relay or relay point. It is used in different contexts to denote a device, location, or process that passes something along—from electrical signals to messages, to trains, or to responsibilities.

In electronics, a relay is an electromechanical switch that uses a coil to magnetically operate one or more sets of contacts, enabling a low-power control circuit to switch a higher-power circuit. Variants include electromagnetic relays and solid-state relays. They provide electrical isolation and are used in automation, protection, and control systems.

In telecommunications and transport networks, a relay (or relay station) is a point that receives a signal, amplifies or converts it, and retransmits it to extend range or coverage.

In sports, a relay is a race where team members each run a segment and pass a baton to the next runner within a designated exchange zone. Common events include 4x100 meters and 4x400 meters.

In hospitality, Relais refers to Relais & Châteaux, a global association of independently owned luxury hotels and restaurants known for emphasis on quality, location, and gastronomy.
