Simple Touch Switch Circuit - to sense the touch event we don t need plex circuits or micro controllers we can sense the touch by using simple touch switch circuit using timer ic 555 here the touch switch circuit sense the event and makes output led glow and it remains in glow for few seconds and then be es off condition touch switch circuit using 555 timer this is a simple touch on and off switch circuit it has a part pares with voltage 2 group in circuit uses an integrated circuit timer lm555 or ne555 span class news dt 15 09 2017 span nbsp 0183 32 supply 12v simple touch alarm circuit using 555 ic here the circuit diagram for a piezo sensor based touch alarm unlike from normal 555 touch plate switch the piezoelectric touch switches are more sensitive and accurate in action p div class b factrow b twofr div class b vlist2col ul li div class b sritem b srtxtstarcolor 5 5 span class csrc sc rc1 role img aria label star.
