Electronic Components: Switches, Fuses and Electronic Modules

Since its creation, Maplin has aimed to be the premier electronic components store, providing a huge range of high quality resistors, capacitors, semi-conductors and other parts. Electronics may have changed in the last 40 years, but our commitment to hobbyists, inventors and learners remains strong. Whether your project is big or small, you’ll find everything you need to realise it right here.

Active, passive and electromechanical components abound in this section. Within our catalogue you’ll find:

  • Resistors (including potentiometers and thermistors)
  • Capacitors (high voltage, variable, ceramic, polarised and more)
  • Optoelectronics (LED light strips)
  • Semiconductors
  • Toggle and rocker switches
  • Automatic relays
  • Transformers
  • Fuses (circuit breakers, fuse wires)
  • Motors and Servos
  • And much more!


In addition to providing individual components, we also stock a range of kits, development boards, lucky bags and the best books on electronic devices and circuits. From the earliest learners seeking GCSE component packs, to advanced users who need circuit simulation software and solderless breadboards, we recognise the importance of being able to quickly and easily prototype new devices.
