120V Incandescent Bulbs
for TW and HW Series
Q: Is there a 120VAC
incandescent lamp for the TW and/or HW series?
A: While we do offer a 120V
incandescent bulb (part number L-120L) that will fit in most TW
and HW series switches, it is not agency approved (i.e. UL, CE,
CSA) in these series and we do not recommend using it. Instead,
use of an LED lamp (LSTD-H2*) or transformer model of the switch
(which will step down from 120VAC to 6VAC) is recommended. These
options also allow for 240VAC and 480VAC (transformer option
only).

Custom Selectors Switches
Q: I need a selector
switch with a contact target table different than any I see in the
catalog. Does IDEC provide custom selector switches?
A: There are many permutations of
contact blocks and operator cams that can be combined to yield a
large number contact closure sequences. Our TW, HW, and TWTD
series are highly configurable. Cam tables in the catalog help
with determining what setup will work for you. We will assemble
custom contact arrangements and assign a unique part number for
each arrangement to allow for future ordering. Contact technical
support for details. Normally lead times will be no longer than
for a standard model.

Four Position Selector
Switch
Q: Does IDEC
manufacture a four and five position 22mm selector switches?
A: Yes, we have these available in
both the TW and HW series. For example HW1S-4TF22N3 is a four
position selector with one contact closure in each of the four
positions. Five position models, such as HW1S-5TF22N3, are also
available, however cam limitations require that the center
position be an "OFF" with no contact closure there. For
more flexibility and positions, a cam switch is suggested as in
our CS series which uses a 30mm panel cutout.

Gold Plated Contacts for
Pushbuttons
Q: Does IDEC offer gold
plated contacts for low level switching on the TW, HW, or TWTD
series switches?
A: We do not offer this option for
these series of switches. The LW series (22mm panel cutout) is
available with gold plated contacts. The TW, HW, and TWTD series
use a self cleaning silver contact that can switch as low as 5mA
at 3V AC/DC, which is much lower than most other manufacturer's
silver contacts. Therefore a gold plated contact may not be
necessary for your application.

Maximum Number Contacts
for TW, TWTD and HW series
Q: What is the maximum
number of contact blocks that can be used with one of IDEC's
switches? I only see part numbers with up to 4 contacts listed in
the catalog.
A: For the TW, TWTD, and HW series the
limit is six (6) contact blocks total, not to be stacked higher
that three (3) deep. Contacts are mounted two (2) per level. Any
combination of normally open or normally closed contact is
possible and extra contacts can be ordered separately and added in
the field.

Quick Connects for TW
contacts
Q: Can I get the
ABW110-B,R,G switch with .250" spade terminations instead of
screw?
A: We do have an accessory that adapts
the TW series contact terminals to a quick connect. The part
number for the .250" adapter is TW-FA1, two are required for
each contact. This is only available in North America. In other
countries you will need to source such an accessory from another
manufacturer.

Three position, three
pole miniature selector switches
Q: Do you have a 3
position 3 pole miniature (16mm) pushbutton? I only see DPDT
listed in the catalog.
A: Although we do only offer DPDT
contact configurations for A6 and L6 pushbuttons, because of the
way the contact closure sequence works, you can produce a 3PST
output (one output per position) via appropriate jumpering.
Requirement is that all 3 loads are of the same voltage.

TW & TWTD Panel
Thickness
Q: What is the maximum
panel thickness for TW & TWTD switches?
A: Six (6) mm.

TW Selector Switch
Operator Cams
Q: What does the -1,
-2, and -3 mean in the TW series selector switch operator switch
part numbers (ASW300-1 , ASW300-2, and ASW300-3)?
A: These numbers refer to different
cam configurations of the operator. The cam configuration together
with the type and mounting position of the contacts determine the
overall contact behavior of the switch. Many permutations are
possible. The "-1 cam" is most commonly used for 3
position HOA switches, and the "-3 cam" is most commonly
used for 3 position 3PST (one contact closure per position)
switches.
