Note: With respect to operating
sequence, pole 1 or 2 may operate
first (virtually same time). If pole
1 or 2 must always operate in a
particular sequence (1 before 2
or 2 before 1), consult factory.
Actuators — Double Pole
Standard type integral hinged lever and
roller actuators are available in choice of
two mounting positions. Actuation lengths
are dimensioned from centerline of switch
mounting hole as shown.

†E20 and E28 actuators are shorter and formed up 15° at the button.
Contact factory for E25 specifications.
Ordering Information
Select the current rating you need. Combine
the corresponding Series/Prefix number
with the appropriate suffix number for the
switch you need. Note: Consult factory for
part number when ordering E19A switches.
Mounting — Double Pole
Recommended mounting screw: #6-32
round head. Recommended torque on
screw: 6 inch lbs. max.

Circuitry — Double Pole
Contact arrangement available in choice of
single pole double throw or single pole sin-
gle throw, either normally open or normally
closed. In general, normally open may be
specified by changing suffix number from
00 to 01 and normally closed by changing
suffix number to 02.
Example: E19-00A is double throw,
E19-01A is normally open, and E19-02A
is normally closed.

QC terminals can be furnished with angle
formed up or down on common as well as
open or closed terminal. Forms include
