Aquarium pump switch Circuit Diagram

Introduction

An aquarium pump switch circuit is an electrical device used to control the flow of water in your aquarium. It allows you to precisely adjust the flow rate of water with the press of a button, and can often be set up to run on a timer for automatic control. This can help keep your fish happy and healthy, allowing you to create a stable environment for them. Unlike air pumps, switch circuits don’t require any outside power source – instead, they cut off the current that’s already in the tank and regulate it so that consistent oxygen levels are maintained. As a result, not only does this reduce maintenance costs for owners, but also helps avoid electrical accidents involving water and electricity.

Working Explanation

of Aquarium pump switch Circuit

The pump in an aquarium is normally switched off when the fish are being fed to prevent the food from being dispersed too widely, which causes much of it to be lost. Such lost food remnants foul up the water. Unfortunately, it is quite easy to remember to switch the pump off when feeding is started, but all too often it is forgotten to switch it on again when feeding time is over.

The circuit shown here ensures that the pump is switched on again
after a certain time lapse. It is based on a 555 timer arranged as a preset monostable multivibrator (MMV). The off time of the MMV can be set between 1 minute and 9 minutes with P1.

Power is provided by transformer Tr1‚, bridge rectifier D4-D7, and reservoir capacitor C3. The rectified voltage is held at 12 V by regulator D3-R8.

The output of the timer (pin 3) controls a relay via T2; one of the make contacts of the relay is connected in series with the supply line to the pump.

The state of the circuit is indicated by D1, D2, and inverter T1. Diode D1‚is on when the MMV is inactive, whereas D2 lights when the pump is switched off.

The pump may be disabled temporarily with a two-way press-button switch S1. This switch may also be used to switch the pump on again before the mono time has elapsed.

The circuit draws a current of only a few milliamperes, excluding the current through the relay.
