    I needed a NC Tactile pushbutton in a project, I layed the PCB design and sent it to the FAB House and then I found that its very hard for them to find the Normal closed Tactile push-button.I needed a push-button that was normally closed (NC) and would open when pushed. Almost every tactile push-button is normally open (NO) and closed when pushed.So, does anyone know of a standard-width, compact-height, through-hole, tactile push-button in a normally closed state? I am using 6mm square tactile Push-button footprint.

    I've never seen a 6mm square thru-hole mount NC tactile switch.

    Congratulations on your new collection of coasters.

    Both Digikey and Mouser carry NC tactile switches, but they are not 6mm square nor thru-hole as per your stated requirements.

    Your omten link on alibaba did not work; this one is correct:
    http://omten.en.alibaba.com/
    and one of the particular 6x6 NC switches: http://omten.en.alibaba.com/product...t_switch_6x6_series_with_2_sidelong_pins.html

    But, that switch is not shown on the manufacturer's actual site:

    Unless you have a LOT of money invested in those boards, you'd really be better off using parts that are industry standard.
