PROTOBOARDS & PHOTO CELLS
For prototype design, testing and modification of circuits. These breadboards will accept the leads of nearly any electronic components (up to
0.032”) in the 0.1” x 0.1” grid of solderless tie points, dual in-line packages, or DIP’s such as I.C.’s plug in for very fast assembly and modifica-
tion of circuitry. Solid wire jumpers plug in for interconnections.
Contacts are a durable alloy with nickel plating;body is made of ABS polymer. Breadboards have indexing numerals on each row and column to
speed assembly and eliminate errors. Ideal for the educator and in the designers lab also.
No. SWS02 - Breadboarding
Wire Kit
Containing several different col-
ors of insulated solid 22 AWG
hook-up wire. Prestripped
lengths for use between tiepoints,
ten pieces of each color supplied
in storage box.

Cadmium Sulfide
PHOTO CELLS
The cadmium sulfide photo
cell has a high resistance in
darkness but resistance is
quite low when in light of 100
foot-candles or more. A typi-
cal use is for switching on
lighting after dark; also used
in alarm systems, exposure
meters, flame detectors, opto-couplers etc.. All three
cells have a dark resistance of 5,000 ohms and 300
ohms in bright light (of 100 cds. or more).
TELEGRAPHERS
(CW code) KEY.
An old standard in a very economical design. Travel distance and ten-
sion are both adjustable. The key should be attached to counter top, a
wood platform etc. Use with code practice oscillators, Ham transmit-
ters.
