You will need the following equipment:
- 2 x DuPont female-to-male patch wires
- Mini breadboard (170 tie points) or a larger one
- Push-button switch (momentary close) or a wire connection to make/break the circuit
- Breadboard wire (solid core)
- 1K ohm resistor
The switches are as shown in the following diagram:
The push-button switch and other types of switch
The switches used in the following examples are single-pole, single-throw (SPST), momentary close, push-button switches. Single pole (SP) means that there is one set of contacts that makes a connection. In the case of the push switch used here, the legs on each side are connected together with a single-pole switch in the middle. A double-pole (DP) switch acts just like a SP switch, except that the two sides are separated electrically, allowing you to switch two separate components on/off at the same time.
Single throw (ST) means the switch will make a connection with just one position; the other side will be left open. Double throw (DT) means both positions of the switch will connect to different parts.
Momentary close means that the button will close the switch when pressed and automatically open it when released. A latched push-button switch will remain closed until it is pressed again.
