Several Lionel accessories, creludans No. ESI Sencar, No. 152 Crossina
Gate, No. 153 Block Signal, No. 45N_ Chiesa and others, can be operated
automatically by the weight of a passing train. This is accomplished through
A
the use of the No. 153C Contactor, one of which is furnished with every auto-
matic accessory.
The No. 153C Contactor is an electrical switch of the “single pole, double
throw” type which is placed underneath the track in such a way that it is
- operated by the weight of the train. Its action is shown in the diagram in
Figure 1. Normally, that is when there is no weight on the Contactor, clip
No. 3 makes an electrical contact with clip No. 1. When the weight af the
train depresses the Contactor, clip No. 3 breaks contact with clip No. 1 and
makes contact with clip No. 2 instead.
In addition to operating automatic accessories the No. 153 Contactor can
be used to control two trains running on one track, for automatic resetting of
switches, and in many other ways which your ingenuity may suggest.
INSTALLING THE CONTACTOR
Slide the Contactor beneath the track so that one of the track ties rests
firmly upon the top contact plate. Any Lionel tubular track except “OO”
Gauge can be used. Do not fasten down track for several sections on either
side of contactor since the track must
remain sufficiently flexible to bend ——__

-The Contactor has no electrical con-
nections to the track itself. After it
is located in the layout it must be con-
nected to the transformer and to the ae 3 :
accessory it is intended to operate. ——_—_— Figure 1—Diagram of the 153C Contactor
