What are Test Switches &

Test Plugs?

Test Switches are devices designed for mounting on

switchboard panels for use in conjunction with proper

test equipment to facilitate the testing of instruments,

meters, and relays.

Test Plugs are multi circuit devices designed to be used with test switches to enable easy measurement, calibration, verification or maintenance of instruments, meters, and relays.

P = Potential, Black; T = Potential, Red; O = Potential, Orange; Y = Potential, Yellow; G = Potential, Green;

B = Potential, Blue; W = Potential, White

C = Current, Non-shorting, Black

R = Current, Non-shorting, Red

C--C, C--C--C, C--C--C--C = Current, Shorting with current test jack right most position, Black

R--R, R--R--R, R--R--R--R = Current, Shorting with current test jack right most position, Red

CO = Current, Orange; CY = Current, Yellow;CG = Current, Green; CB = Current, Blue; CW = Current, White Note: Some functions will require more than one slot in the switch body

Step 2

If a tie bar is required check this box

and draw a dark heavy line over the poles to be joined.

In the example above positions H, I, & J will operate together.

Step 3

Select a cover style

Clear (Installs over open or closed switches)

Black (Installs over closed switches only)

Step 4

Select a rear terminal type

Screws (Standard)

Studs (Optional)
