WebHence t = 1.1 x 1010K x 100u = 100 seconds. When pin 4 of the LM555 is triggered (by shorting it to ground) through the momentary switch S2, the timer is reset. When the timer starts, the relay turns ON. Hence the Common (COM) terminal of the relay is shorted to the Normally Open (NO) terminal. Web2 de jan. de 2010 · It’s not the greatest for battery-powered applications. When “off” it draws about 4-6mA, depending on the brand of 555 timer chip you use. When on it draws that plus whatever power the switched device draws. Best to put a proper power switch on the battery pack to eliminate this quiescent drain.
