Our old house has push button light switches. I would like to find some modern replica switches and face plates for use in some electrical improvements. I have checked at our local home improvement stores and our one (very small) local electrical supply house they did not have any. Is there a online source?
Amazon shows them as available. Search for 'push button light switch' to find more variants (including 3 way and dimmer units).
