Quiz on Switching Circuits and Symbols 2

What does the term 'normally opened' refer to in switch terminology?

• The switch is open until pressed, then closes.

• The switch remains in the closed state when pressed.

• The switch is always closed.

• The switch can control multiple circuits.

What is a single-pole single-throw (SPST) switch?

• A switch that can control two circuits.

• A switch that can connect to multiple outputs.

• A switch that changes connections between two wires.

• A basic on/off switch for a single circuit.

What does a double-pole switch control?

• A single circuit with multiple outputs.

• Three circuits in sequence.

• Two circuits simultaneously.

• One circuit only.

What is the function of a momentary contact switch?

• It is used for high voltage applications.

• It can control multiple circuits at once.

• It only connects when pressed and returns to its original state.

• It remains in the last position until manually changed.

What is the purpose of the common terminal in a double-throw switch?

• To serve as the input terminal.

• To act as a ground connection.

• To connect to one of two output terminals.

• To connect to the power source.

What happens when a normally closed (NC) switch is pressed?

• The lamp will light up.

• The switch remains in the closed state.

• The switch becomes normally opened.

• The circuit is interrupted.

What is a three-way switch also known as?

• A single-pole single-throw switch.

• An A/B switch.

• A double-pole switch.

• A momentary contact switch.

How many terminals does a double-throw switch have?

• Three terminals.

• Two terminals.

• Five terminals.

• Four terminals.

What is the main characteristic of a maintained contact switch?

• It changes state and stays in that state when the force is removed.

• It only works when pressed.

• It has no moving parts.

• It can only control one circuit.

What does the term 'throws' refer to in switch terminology?

• The number of different switching positions a switch can be in.

• The voltage rating of the switch.

• The number of circuits a switch can control.

• The type of materials used in the switch.
