MICRO SWITCH™ BX Series
SPECIAL CONDITIONS FOR SAFE USE
Honeywell explosion-proof switches are designed specifically
for use in hazardous location applications. The BX enclosure is
sealed for protection against corrosion, water, dust and oil as
defined in NEMA 1, 3, 4, 4X, 6, 13, and IP67 (per IEC60529). The
temperature rating for these products depends upon the seal
material used. Products using a fluorosilicone seal have a rating
of -40 °C [-40 °F] to 70 °C [158 °F]. Products using a fluorocar-
bon seal have a rating of -12 °C [10 °F] to 70 °C [158 °F]. MICRO
SWITCH™ BX switches are rated according to the electrical rat-
ings detailed in Table 1.

The maximum construction gap (ic) is less than that required by
Table 2 of EN/IEC60079-1:2007, clause 5.2.2 as detailed below
in Table 3.
The equipment has a non-conducting coating and may generate
an ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the equipment
is not installed in a location where it may be subjected to external
conditions (such as high pressure steam) that might cause a
build up of electrostatic charges on non-conducting surfaces.
Additionally, cleaning of the equipment should be done with a
damp cloth.

American Hazardous Locations Designation: NEMA 7 - Class I,

comply with UL Standard: UL 894, CSA Standard: C22.2 No. 25-
1966, C22.2 No. 30-M1986.
The BX is ideal for outdoor use or in adverse environments where
a combination of explosion-proof plus sealing requirements are
needed. To comply with explosion proof requirements the BX
has flame paths within the housing, which cool exploding gases
below the ignition temperature before they reach explosive gases
surrounding the housing. Flame paths on the BX are (1) an ex-
tended plunger between the switch cavity and head and (2) the
cover-housing threads on the front of the switch.
MOUNT, ADJUST, WIRE
MOUNTING
Note mounting dimension drawings for hole locations (Fig. 9,
page 3). The BX is directly interchangeable with the LSX explo-
sion-proof limit switches: Adapter plate is not required.
ADJUSTING INSTRUCTIONS
To give flexibility in application, the user can perform the adjust-
ments described below in any order before wiring the unit.
ACTUATOR HEAD
The actuator head may be positioned in any of four directions.
1. Loosen the four captive head screws.
2. Place head in the desired position.
3. Securely tighten the four screws to 1,4 Nm to 1,8 Nm [12 in-
lb to 16 in-lb] (Figure 1).
REVERSING THE ROLLER LEVER
Except for the offset roller levers, the roller arm may be reversed
to face the roller to the inside or outside of the arm.
