Colours span blue, green, red, red-blue, red-green, white and yellow, and there are actuator heights from 0.35 to 6.3mm, operating forces from 160 to 300gf, and lives up to 100,000 cycles.
“These illuminated tactile switches carry surface mount or through hole mounting styles, pin or gull wing terminations, and vertical or right-angle orientations,” said the company.

Picking the surface-mount TS21-34-035-BK-260-SMT-TR (pictured) almost at random, it is one of the 3.4 x 3.4 x 1.5mm switches, with the 260 indicating 260g force needed for operation – there is also a 160g version.
Ratings include 1 – 12Vdc and 10μA to 50mA operation, and 100mΩ contact resistance (5V, 10mA, 520g force).
Expected life is 100,000 cycles (5V, 5mA, 390g force).
The TS21-34-035-BK-260-SMT-TR data sheet can be found here, and this CUI-provided parametric search should bring up the new illuminated parts at the top of a table.
