Hello,
I'm looking for a particular pushbutton manufacturer or a high quality replacement. I'm sitting in front of an intercom device which has exactly the type of button I prefer, but I'm probably not allowed to open it. (See attachments) There is a small one with a completely flat surface and a big one which is pretty flat but has a very shallow, round depression in the middle. The surface is transparent, but slightly dull. I don't know if they are PCB-Mounted and if the cap and button are separate parts or one assembly.
The small one is about 11 x 11 mm.
The big one is about 17 x 17 mm.
They both feel pretty much the same. A very uniform travel of about 4-5 mm without a tactile click.
The requirements are:
- No bezel, so the button protrudes through a frontplate, but not attached to it
- Illuminated
- Square and flat front
- Large flat "view" area and possibility to insert a text film strip
- No tactile click
- High quality, high cycle counts
- Momentary
- No special, or high amp / voltage ratings (digitally captured)
I have gone through the following manufacturers. None of them seem to be exactly the same, but some come pretty close.
E-Switch / EAO / Siemens APT / Panasonic / CIT JC / Omron
What I'm not very familiar with yet is the combination of
PCB-mount buttons + a separate cap as an assembly. I haven't yet looked into the separately svailable caps there.
Help, or suggestions for more manufacturers is very much appreciated!
