Deck 17: Switch Control of Lighting Circuits

Question 1

A three-way switch contains one common terminal and three traveler terminals.

Answer 1

False

Question 2

You are constructing a circuit where a group of lights must be controlled from more than two switching points. What kinds of switches will you use?

Answer 2

The four-way switch is used when a group of lights must be controlled from more than two switching points. The switch connected to the source and the switch connected to the load must be three-way switches. At all other control points, four-way switches are used.

Question 3

United Laboratories, Inc. classifies toggle switches used for lighting circuits as general-use snap switches and divides these switches into four categories.

Answer 3

False

Question 4

It is often convenient to be able to control a hall light from either an upstairs or downstairs location, or a garage light from either the house or the garage. In either of these circumstances, the best choice would be a(n) ____________________ switch.

Question 5

Category 1. AC/DC general-use snap switches may control tungsten filament lamp loads not to exceed the ampere rating of the switch at _________________________ volts when marked with the letter T.

Question 6

A(n) ____________________ switch is used when a light or group of lights, or other load, must be controlled from one switching point.

Question 7

A three-way switch has one terminal, called the common terminal, to which the ____________________ is always connected.

Question 8

The three-way switch has no ON or OFF position.

Question 9

The AC/DC general-use snap switch is usually marked AC/DC.

Question 10

What determines whether a toggle switch is classified as a Category 1 or Category 2 switch as defined by United Laboratories, Inc.? How can you tell by looking at a switch if it is Category 1 or 2?
