Relays consist of a solenoid which can be driven from a smaller signal to make a physical connection between switch contacts.

Modules

Sometimes relays can have weird footprints, or require some extra components to interface with a microcontroller, that's what relay modules are for!

  6. Solid State Relay - 40A (3-32V DC Input)
    Rating:
    99% of 100
    SKU: COM-13015 Brand: Sparkfun
    A solid state relay (SSR) allows you to control high-curent AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.
