Frequently Asked Questions For IDEC Switches
IDEC Corporation 12th Dec 2022
Is there a 120VAC incandescent lamp for the TW and/or HW series?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).
I need a selector switch with a contact target table different than any I see in the catalog. Does IDEC provide custom selector switches?
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.
Does IDEC manufacture a four and five position 22mm selector switches?
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.
Does IDEC offer gold plated contacts for low level switching on the TW, HW, or TWTD series switches?
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.
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.

Can I get the ABW110-B,R,G switch with .250" spade terminations instead of screw?
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.
Do you have a 3 position 3 pole miniature (16mm) pushbutton? I only see DPDT listed in the catalog.
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.
What is the maximum panel thickness for TW & TWTD switches?
Six (6) mm.
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)?
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.
