Wiring accessory (mecanismo eléctrico)

The visible end part of the installation that you operate: switch, two-way switch, push button, socket, TV or data outlet and dimmer. It is made up of a module fixed to the wall box, a rocker or cover and a frame. In US English, a wiring device.

What a mecanismo is

In Spanish electricians’ language a mecanismo is any piece on the wall you touch to use the installation: switches, two-way switches, push buttons, sockets (outlets), TV and data outlets, dimmers and doorbell buttons. In the UK they are wiring accessories; in the US, wiring devices. They are the last thing fitted on a job and the most visible.

Parts

  • Module: the part with the terminals, screwed or clawed into the flush box.
  • Rocker or cover: what you press or plug into.
  • Frame: the trim around it, single or multi-gang.

Each manufacturer has its own ranges, and rockers and frames from one range do not usually fit another. To replace just one, it helps to know the brand and model.

When to replace them

  • Broken rockers or ones that do not make good contact.
  • Loose sockets that do not grip the plug, or with scorch marks.
  • Accessories that get hot or crackle.
  • Old sockets without earth.
  • A cosmetic refresh: new accessories transform a flat (apartment) with little work.

A hot or blackened socket is not a cosmetic problem: it is a poor contact that should be checked soon.

Special types and cost

There are models with USB ports, pilot lights, weatherproof versions, LED dimmers and smart wifi or Zigbee switches. As a guide, a simple accessory costs 30 to 50 euros plus VAT fitted, depending on the range. See handyman electrician in Seville, Spain.
