If this is the "feel" that is desired, customised metal dome overlay sheets can be ordered (minimum quantity 1000+) via alibaba. Example offer here They list a price range of $0.19 to 0.21 each, but it isn't clear to me whether that is per dome, or per sheet of domes. If it's per sheet, that's a great deal, assuming that you're going to make hundreds of calculators. The XC-42 hardware Richard Ottosen and I are developing uses Alps SKRPABE010 surface-mount tact switches which I've recently been able to source for $0.13 each in quantity 500. The XC-42 has 44 switches total, so that's $5.72 of the parts cost of the unit. Avnet lists them at $0.0784 each in quantity 4000. |
