Installed in the Acer Aspire 2920 notebook. Does not work at all - pushing at any angle has no effect. Second button (left touchpad one) works properly.

Circuit diagram lists SW-TACT-119-GP / 62.40009.671. Can not find anything using these numbers other than various Wistron circuit diagrams.

Dimensions are (approximately) 6 * 6 * 3 (mm).

Update:

After taking the closeup pictures I thought that according to the construction the buttons seem to be maintainable. I disassembled all of them - without desoldering the device (only desoldering the top metallic cover's pin), cleaned, assembled back, and now all the buttons function properly.

    \$\begingroup\$ The most critical dimension in this case is the height above the board. Also pay attention to the operating force. \$\endgroup\$ – Spehro Pefhany Sep 17 at 17:18

My guess is its a TE connectivity part, maybe one like the one shown above.
