Usually, touch faucets function through a unique type of sensor. This sensor detects whenever a hand moves against the faucet. This type of faucet augments your convenience level while cleaning dishes and washing things. If both hands aren’t free to operate the kitchen sink faucet, you can simply touch it to switch on. It’s one of the primary benefits of a touch faucet. Wondering how do the touch faucets work? If you are seeking to get precise knowledge on the functioning of touch faucets, just read on.

Significant Parts of a  Touch Faucet

Touch Faucets are extremely simple to use. By touching the handle or the spout of the faucet, you can turn on or off the water flow. To understand how do touch faucets work, you need to be aware of the key parts of the faucet. One must start with the basics before jumping into the actual working procedure of a touch faucet. Let’s go through the working procedure of a touch faucet’s internal parts in this post. 

1. Sensor

Touch faucets usually come with a built-in sensor. A specific sensor is arranged either in the spout of the faucet or in the rim of the spout. The functionality of a sensor is to detect the hand motion when it gets closer to the faucet. Two sensors are usually present in touch faucets. One sensor will be placed in the handle and the other sensor in the spout of it. As it is a touch-specific faucet, it turns off automatically when you remove your hand from the faucet. Moreover, the sensors are designed in a highly sophisticated manner. You don’t need to grab it hard. Instead, just place your hand gently on it. It recognizes your touch and starts flowing the water. This way, the sensor works with a simple touch. 

2. Spout

A spout works as a shelter for the functioning parts of your faucet. The spout must be of high quality and sturdy. This ensures the long-term functioning of the sensor, batteries, and valve within the spout. Mostly, touch faucets are made of various materials such as copper, zinc, brass, and others. The costly touch faucet models are made of brass material quite often. Moreover, to remain conductive, these touch faucets are usually made of brass material. Besides the material, the touch faucet finish will be done through chrome or nickel. Such faucet finishes ensure the longevity of the faucet. Moreover, it renders an elegant look to the faucet and gains the attention of your guests. 

3. Electricity

You don’t need to set up an external power source for operating the touch faucets. They usually work on battery power. To be precise, a touch faucet requires electrical energy which is essential to make the sensor work accurately. An integrated battery in a touch faucet must be adequate power to operate the faucet regularly. These types of faucets depend on DC power source and it uses 1.5 Volts batteries. Some other touch faucet models may need about 9 volts of DC. 

4. Touch Technology

The touch faucets are designed based on ‘capacitive sensing’ technology. It’s nothing but detecting the normal capacitance of a body. The sensors present in the faucet will have the ability to detect the capacitance of the body when it gets closer. Eventually, once we touch it, the sensors detect through capacitive sensing technology.

In short, capacitance is the device’s ability to catch an electrical charge. Similarly, the human body also acts as a capacitor and has the ability to store some amount of electric charge. As a result, the electric charge present in our body will be reacted whenever a faucet is touched. The human body’s capacitance is enough to make your sensor recognize the touch and operate accordingly. By the way, similar capacitive sensing technology is witnessed on touchscreen smartphones.

5. Solenoid Valve

Most touch faucets comprise a solenoid valve that operates alongside the sensors. This valve works based on the signals given by the sensor present in the faucet. As mentioned earlier, the sensor acts as an electromagnet that regulates the water flow based on capacitive sensing. The solenoid valve opens soon after receiving a signal from the sensor. For instance, you placed your hand on the faucet’s handle. Immediately, the valve gets opened allowing the water to flow through the faucet. If you remove your hand, the valve gets closed stopping the water flow.

By now, you might have understood the significance of every part of a touch faucet. Now, you can read further to know how do touch faucets work. Get to know the complete working mechanism of a touch faucet in this guide.

How Do The Touch Faucets Work?

To help our readers understand the working mechanism of a touch faucet, we try to explain it in a simplified form. 

  • Touch faucets usually run based on capacitive sensing technology. It’s a fact that the human body has a slight electrical charge. The human body that holds this sort of electrical charge is known as capacitance. 
  • The capacitance of a human body is measured in Farads. In general, a human body’s capacitance ranges between 100 and 200 picofarads. 
  • In this technology, the sensor translates the abrupt changes that occur in the capacitance. 
  • To make it simple, whenever you touch the faucet, the sensor present in it immediately detects the capacitive charge produced from your body. This charge triggers the solenoid valve in the faucet. It eventually turns the faucet on or off. It, in turn, triggers the water flow through the faucet.
  • The sensor plays a vital role in the working mechanism of a touch faucet. The role of a sensor is to measure the capacitance that’s usually generated from the human body. Its capacitance range rises whenever you touch the handle of your faucet to activate the flow of water. The capacitance will then reduce when you touch the faucet once again to stop the water flow. 
  • As mentioned, the touch faucets come with two integrated sensors. One sensor is placed in the handle and the other in the spout. These sensors are attached to any conductive material i.e., brass or other material of the faucet. Hence, the sensor gets triggered when your hand or body contacts with the faucet.
  • Most of the touch faucets switch on by touching it once. To stop the flow of water, just touch it the second time.

Note: Make sure that no metal comes in contact with the touch faucet as it works on a sensor. Otherwise, the sensor may not work properly.
