Spade-Terminal Relays
Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.
Surface mount relays, also known as power relays, have a slot on the flange for mounting them to flat surfaces.
Relay-socket mount relays, also known as ice cube relays, offer three ways to connect. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals.
Relay-socket/surface mount relays can plug into a socket or mount to a flat surface.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They can also mount to a flat surface.

Circuit Board Relays
Smaller than relays with electrical wiring, these relays fit in compact devices. Mount them through holes on circuit boards with their solder pin terminals. Use them to control heaters, fans, and other high-power components from a low-power circuit.
