8.2
An electrical switch that stays in its last on or off position without power
  • noun
  • Specialized
translation icon : relé de retención
  • Unlike standard relays, a keep relay does not consume power to maintain its state.

Examples

  • The technician installed a keep relay to ensure the lights stayed on during a power interruption.

  • In industrial controls, a keep relay is often used for safety circuits requiring memory.

  • The keep relay ensures the circuit remains active.

  • Can you explain how a keep relay works?

  • In industrial applications, a keep relay holds its position even when power is removed, maintaining circuit continuity.

  • The engineer chose a keep relay for the control system so that the lights would remain on during brief outages.

  • To enhance reliability, the design includes a keep relay that keeps the system operational without needing constant electricity.

Morphology

keep + relay

Knowing 'keep' (to continue or retain) and 'relay' (an electrically controlled switch) lets a learner infer a relay that "keeps" or maintains its state, so the basic idea is derivable. However, the precise technical sense—that it latches after the coil is de-energized and needs no continuous power—is specialized and not fully predictable from the constituents or everyday composition patterns, so a B1 learner would only get a partial understanding.

Etymology

Keep relay comes from the simple idea of a keep (something that holds) and a relay (an electrical switch): it is a device that stays in the same position even after the power goes off, like a door that stays closed after you shut it. That's why a 'keep relay' means a relay that 'holds its state' without needing continuous power.
