The relatively small current in the input circuit thus activates the larger current in the output circuit:
- The input circuit (blue loop) is switched off and no current flows through it until something (either a sensor or a switch closing) turns it on. The output circuit (red loop) is also switched off.
- When a small current flows in the input circuit, it activates the electromagnet (shown here as a dark blue coil), which produces a magnetic field all around it.

What happens when power goes through a circuit?
When power flows through the first circuit (1), it activates the electromagnet (brown), generating a magnetic field (blue) that attracts a contact (red) and activates the second circuit (2). When the power is switched off, a spring pulls the contact back up to its original position, switching the second circuit off again.
What is a normally open relay?
This is an example of a "normally open" (NO) relay: the contacts in the second circuit are not connected by default, and switch on only when a current flows through the magnet. Other relays are "normally closed" (NC; the contacts are connected so a current flows through them by default) and switch off only when the magnet is activated, pulling or pushing the contacts apart. Normally open relays are the most common.
How does a magnet work in a programmer?
The electronic circuit in the programmer switches the magnet on or off at preprogrammed times of day using a relatively small current. That allows a very much bigger current to flow through the spring contacts to power the element that heats the hot water.
