About Timer Relays

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.

Solid State Surface-Mount Timer Relays
Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
Delayed start (delay-on-make) relays allow you to set how long it takes for the relay to turn on after input voltage is applied. For example, a drill starts pumping a lubricant immediately, but it does not start rotating until the set time has elapsed.
Switches with a potentiometer (variable switch) allow you to adjust the delay within the range.
