Once that is shorted with a switch, the 0,1µ and 10µ are in parallel, totalling at 10.1µ. Point of the 1M is to prevent noise from flicking the switch.<br />+mmirosolhttps://www.blogger.com/profile/02400327798106357876noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-69464409925894672552017-12-11T18:54:10.495+00:002017-12-11T18:54:10.495+00:00Was not aware of that.
