LS-Titan Safety Interlock Switches
Product Description
1
Eaton’s LS-Titan™ safety
interlock switches have been
1
specifically designed for
monitoring the position of
1
protective guards, such as
doors, flaps, hoods and
1
grilles. All switches in this
family are safety-rated,
include positively opening
1
NC contacts, and cannot be
defeated using simple tools,
1
such as pliers, screwdrivers
and nails.
1
The LS-Titan safety interlock
family is comprised of three
1
types of safety switches: key
interlock, door-flap and door-
1
hinge switches.
Key interlock switches are a
1
two-piece design, made up of
the switch and key (actuator).
1
The key portion of the switch
is affixed to a movable door,
1
cover or other such guard.
The switch itself is mounted
1
to a rigid portion of the
machine. When the guard is
opened, the key is removed
1
from the switch, thereby
positively breaking the NC
1
contacts. This interrupts the
control circuit, stopping
1
machine operation.
The door-flap and door-hinge
switches are one-piece
designs, suitable for when a
key cannot be mounted in the
application. When an attempt
is made to open a protected
door hinge or flap during
operation, these switches
disconnect the power supply
to the machine or installation.
Both switches feature fourway adjustable heads.
All LS-Titan safety interlock
switches are approved to
protect personnel and
processes.
