MICRO SWITCH Specialty
Limit Switches.
Application-proven specialty
limit switches for swing-door
applications:
Relialign™ Series
Residential Door Interlocks
are designed for use in
residential swing door
applications, specifically
dumbwaiters, lifts for the
mobility impaired and swing-
door elevators in the USA. In
Canada, the RDI is designed
for use in residential swing
door applications, specifically
elevators and dumbwaiters
but is not designed for use in
lifts for the mobility impaired.
The interlock holds the door
in place and prevents it from
being opened in potentially
unsafe conditions (e.g. the
elevator/lift car is not present
at the door). A number of
design features contribute
to increase safety, reduce
nuisance stoppages and
call-backs, and contribute
to simplified wiring and
installation. Featuring a
custom internal solenoid
control, the RDI may reduce
complexity of the host
controller, reduce power
consumption for a “greener”
product, extend solenoid life
and reduce solenoid “time
outs,” reducing customer
aggravation.

actuator seal boots. Both have a
combination insulator/seal cemented
inside the bottom enclosure. Lead
washers are used to seal the mounting
holes on side mount switches. All side
mount switches are installed with
#6 screws, except the BZE6-2RN7
(#8 screws). Removal of the bottom
enclosure exposes the terminals for
easy wiring. Applications include
packaging equipment, textile machinery,
construction equipment, printing
machinery, and more.
