1 Overview
HY series reversing switch (hereinafter referred to as
switch) is suitable for AC 50Hz (or 60Hz) circuits with
rated operating voltage up to 380V and with rated
operating current up to 20A, and is primarily used to
directly turn on/off a single squirrel cage induction motor
for start, run, stop, and reverse rotation.
This series of products comply with the standard
GB14048.3 "low-voltage switchgear and controlgear -
Switches, disconnectors, switch-disconnectors and
fuse-combination units".
The product has obtained 3C certification certificate.
The normal operating conditions of the switch are as
follows:
a) The ambient air temperature does not exceed +40°C
and the lower limit of its ambient air temperature is -5°C,
and the average temperature within 24 hours does not
exceed +35°C.
b) The altitude of the installation site does not exceed
2000m.
c) Atmospheric relative humidity at the switch
installation site does not exceed 50% when the ambient
temperature is +40℃, and a higher relative humidity is
allowed at a lower temperature, such as 90% at 20°C.
Special measures are taken for condensation generated
occasionally due to temperature changes.

d) Pollution level: Level 3.
e) Usage category: AC-3.
f) Protection grade: IP20.

3 Structure Characteristics and Electrical Schematic
Diagram
The switch primarily consists of a handle, a cam, and
contacts. Cam and contacts are installed in the housing.
There is a total of 5 pairs of contacts, and they are
double-break bridging contacts, of which one pair is used
to control the forward and reverse rotation, two pairs are
used to control the forward rotation, and the other two
pairs are used to control the reverse rotation of motor.
Turning the handle will drive the cam rotate, thereby
making or breaking the contact.
The electrical wiring diagram of switch is illustrated in Fig. 1.

5. Installation, Operation, and Maintenance
a) Before installation, check the rated operating current
is consistent with the contract, and check the product for
damage or integrity.
b) The switch should be installed inside the circuit
control switch and fuse. No overload, short circuits or
no-voltage protection is provided for this switch. Its
wiring connection is shown in Fig. 1. Do not install it in
a place whether there is too wet or there is corrosive gas.
c) The switch cannot be used for frequent braking.
d) The metal shell must be grounded.
e) The switch is not suitable for hoisting or lifting
equipment.
f) When the motor is in a forward rotation state, to make
it rotate reversely, turn the handle to the "Stop" position
to stop the motor, and then turn the handle to the
"Reverse" position from the "Forward" position to rotate
it reversely. The stator winding of motor will generate a
very large inverse current due to the sudden reverse
connection of power supply, which easily cause damage
to the motor stator winding due to overheating.
g) Please often check the contact surface and rotating
mechanism during the operation of switch (turn off the
power supply before check); if found that the contact is
burnt or the rotating mechanism works inflexibly, please
timely repair it before use; if the mechanism is rotating
inflexibly, an appropriate amount of grease shall be
applied between the cam rollers.
