    Super Capacitor Questions

    I have questions on the lifetime of EDLC's, or electric double layer capacitors. I've read several data sheets online from suppliers but don't have an accurate description of their life. Most give + or - some value after 1000 hours of operation. Does this just drop the capacitance if operated...

    Stupid question probably I am using a 120 ac single phase motor, a NC switch opens when a cam hits. I want to use the NO part of the switch to ground an input to a microcontroller (24 Vdc). What implications are there if the common part of the switch is tied to the Vdc- and AC neutral of the...
