पानी की टंकी मोटर स्वचालित चालू / बंद स्विच  प्रस्तुत सर्किट द्वारा पानी की टंकी पूरी तरह से भर जाने के बाद टैंक की मोटर अपने आप बंद हो जाती है। और टंकी में पानी खाली होने पर मोटर अपने आप चलने लगती है।  इस परिपथ में IC 555 का प्रयोग किया जाता है। IC 555 इस सर्किट और टाइमर सर्किट दोनों में समान रूप से काम करता है। और IC सुरक्षा के लिए, हमने इसमें एक डायोड in4007 जोड़ा है। इसके अलावा इस सर्किट में 2 ट्रांजिस्टर BC548 का भी इस्तेमाल किया गया है। और एक रिले 18V का उपयोग ऑन-ऑफ स्विच के रूप में किया गया है। इस परियोजना में हमें तीन तारों को पानी की टंकी में विसर्जित करने की आवश्यकता है। +V तार को पानी की टंकी के सबसे निचले स्तर पर रखा जाना चाहिए और ic के ट्रिगर पिन 2 वाले तार को पानी की टंकी के मध्य स्तर पर रखा जाना चाहिए। और तीसरा तार जो ट्रांजिस्टर Q1 के आधार से जुड़ा है, पानी की टंकी के शीर्ष पर रखा गया है। काम करने का ढंग पानी की टंकी मोटर ऑटो चालू/बंद स्विच
