DI-102
is governor
switch used
for detecting
overspeed,
which cuts
the power
of electric
motor and
stops elevator
car if elevator
car operates
at over the
normal speed
and speed
indicator
points dangerous
speed.
Before elevator
car exceeds
130% of regular
speed, turn
governor switch
open and cut
the power
of electric
motor and
before over
140%, governor
switch is
turned open
and catch
governor rope
and operates
emergency
stop.
Features
1. It has
acquired movement location
with detail level and built-in
micro switch
2. Impact
and vibration aren¨t given
to contacts by using actuator
so that we can assure mechanical
intensity.
3. As a
rod lever type, it detects
overspeed
4. It maintains
stable detail contact resistance
for thermal resistance
5. Case
is made of steel so that
it is protected from external
force
6. It
makes wiring easier in the
state of being installed
to governor.

Application
It
is installed to
governor as shown
in right feature
and
before
ascent or descent
speed of elevator
car arrives at

catch, elevator
lifter should be
