M-23A, M-23B, M-3 and Low-Profile M-3
Electric Switch Machines
ASTS USA’s style “M” Electric Switch Machines are
rugged, reliable, units designed for any installation
where electric power is available. The M-23A and M-23B
units have dual control features, including a hand-throw
lever to permit operation by on-site trainmen or
maintainers, as well as by remote controlled power.
The standard and Low-Profile M-3 Switch Machines are
recommended for applications where there is seldom a
need to manually operate the switch. These three
machines are available with a variety of operating
speeds, gear ratios and motor voltages. Numerous
circuit controller configurations are also available, both
mechanical and electronic.

General Description
Key Options
Style “M” Electric Switch Machines are available with a
numerous features and options to suit customer needs.
These include various operating voltages, gear ratios, throw
times and control wiring schemes as shown in the ordering
tabulations. Basic differences include the following:
Basic Design
Style “M” Electric Switch Machines consist of a motor, a
gear train, a cam arrangement (for operating the switch and
locking) and a circuit controller. All of these machines use
the same basic casting, and are interchangeable with
respect to mounting and connections in a switch layout.
However, the M-23A and M-23B machines require a
somewhat higher clearance than the standard M-3 or Low
Profile M-3. Both models of the M-3 Switch Machine can be
operated by hand by inserting a temporary crank.
For installations where extra vertical clearance is needed,
the Low Profile M-3 Electric Switch Machine is
recommended. This machine is similar to the standard M-3
in design and operation, but is 5/8-inch (1.58 cm) lower in
vertical dimension. This small but important height reduction
makes the Low Profile M-3 ideal for third-rail transit
applications where additional clearance is needed for the
vehicle pick-up shoe. The point detector bar can be

vertically lifted from the machine, allowing easy handling in
tight confines. Left and right-hand versions of this machines
are available, each with a single operating voltage, gear
ratio and wire control scheme.
The M-23A uses a different hand-throw pinion than the M23B, which affects hand-throw locking. Power operation is
the same with both machines. In the M-23A, the hand throw
lever gives the same mechanism stroke and full lock rod
protection as the power operated mode. In the M-23B,
however, the lever does not provide lock-rod protection
(slide bar and lock box do not move full stroke).
All “M” style machines are wired at the factory, with internal
wiring connected to a main terminal board in the motor
compartment. A typical wiring diagram or working drawing is
enclosed with each shipped machine to show how external
connections should be made to the main terminal board for
a particular application.
Motor and Gear Train
ASTS USA “M” Electric Switch Machines use a fully
enclosed, permanent magnet motor. This type of motor
provides lower inductance, better EMI immunity and higher
efficiency than previous field wound motors, and
incorporates simpler 3-wire control. (Permanent magnet
motors are also available for retrofitting older models of
these switch machines; see RSE-6A4.)
The gear train in the “M” style Switch Machines is comprised
of a pinion on the end of the motor shaft, one or two
reduction gears, clutch gear, friction clutch, worm shaft and
worm gear. Three different gear ratios are used to provide
three operating speeds: 189:1, 360:1 and 528:1. The Low
Profile M-3 incorporates the same basic gear train concept
as the other style “M” machines, and is provided with a
single gear ratio of 189:1. In all style “M” machines, a
friction clutch protects the mechanism from the shock
incurred at the end of a stroke, or when an obstruction is
present. For complete motor and gear train specifications,
refer to the ordering tabulations.
Mechanical Circuit Controller
The mechanical Circuit Controller used in the style “M”
switch machines has four pairs of contacts. Two motor
control contacts are wired internally. The remaining are
indication contacts for external switch position
determination. To allow standardized wiring, provision is
made to always have certain contacts set as normal,
regardless of which end of the operating stroke is
designated as normal.
Machines equipped with an mechanical circuit controller
include a point detector with latch device. A latchout kit is
available for the point detector mechanism (see RSE-6A4).
Components in this kit enable the circuit controller indication
contacts to be held open (until reset) when the point detector
bar is displaced while the machine is in locked-up condition
(i.e. switch points obstruction).
RSE-6A3, p. 2
ECC+EBNC or ECC+MCU
ASTS USA offers models of its standard M-3, M-23A and M23B switch machines outfitted with an Electronic Circuit
Controller (ECC), in conjunction with an Electronic Biased
Neutral Controller (EBNC) or Motor Control Unit (MCU). A
true linear detection device with no moving mechanical parts
to maintain, the ECC eliminates circuit-controller sensitivity
degradation due to component wear. The ECC utilizes
inductive proximity sensors to continuously monitor switchmachine conditions. It vitally monitors the position of the
switch points and the internal locking mechanism, delivering
switch-machine indications to the wayside. For more
information on this device, refer to RSE-6F3.
ASTS USA can also add the ECC unit into existing
machines returned to the factory for refurbishment; refer to
the RSE catalog introduction for more information on this
service, or contact your ASTS USA Account Executive.
The EBNC is used in the M-3 machines with ECC to enable
direct control of the switch machine using a bipolar output of
a vital logic controller such as the MicroLok® II or the
MicroLok® Object Controller. In an EBNC-equipped
machine, the motor power is fed from a fixed polarity source
(direction determined by the EBNC). In the M-23A and M23B machines with an MCU, motor power is fed from a
bipolar source (direction determined by the wayside control
equipment). The M-3’s EBNC includes a motor overload
protection function. Overload protection for the M-23A/B’s
MCU is provided by the wayside control equipment. Existing
installations using 3- or 5-wire control are converted to 2wire control when installing an M-3 ECC/EBNC or M-23A/B
ECC/MCU machine.
Independent Point Detection (IDP)
Selected models of the M-3, M-23A and M-23B switch
machines (with mechanical circuit controller) are equipped to
provide independent point detection. With this feature, the
point detection mechanism senses the position of the near
and far switch machine points independently to ensure that
both are in the proper relative positions to each other and
the rails. Thus, any mounting problems or unwanted slack
in the connecting rod between the points are detected. (In
other switch machines, only the nearest switch point
movement is monitored).
M-3 Machines for Replacement of Alstom Machines with 2Wire Control
Four versions of the M-3 Switch Machine with mechanical
circuit controller can be used to replace selected Alstom with
2-wire control. Refer to ordering tabulation on page 12 for
specific part numbers. Contact your ASTS USA Account
Executive or request Service Manual SM-6263 for additional
information.
