Switches are used in countless electronic devices, ranging from lamps and overhead light fixtures to TVs, computers and more. By definition, a switch is an electrical component that’s used to control a circuit. When the switch is pressed, the circuit closes. When the switch is released, the circuit reverts back to its open state. There are different types of switches, however, one of which is a touch switch.
Electrical switches are used in a variety of electronics and devices. As you may already know, their primary purpose is to control the flow of electrons in a circuit. Switches contain two modes: closed and off. When the switch is closed, the circuit is complete, thereby allowing electrons to flow. When it’s open, the circuit is broken and the electrons are interrupted. An essential component used in electrical switches, however, is an actuator.
If you’re looking to buy a switch — whether it’s for a human machine interface (HMI), industrial equipment controls, a remote controller, etc. — you should consider choosing a capacitive switch. Using the same capacitive technology as touchscreen tablets and smartphones, it’s a unique alternative to traditional dome switches. With dome switches, physical contact between the key and an underlying circuit trace is needed to register a keypress. Capacitive switches differ in the sense that they identify keypresses via the user’s touch. So, why should you choose a capacitive switch?
Switches are the foundation on which electrical devices, including touchscreens, operate. In the most basic sense, a switch is a component that controls an electrical circuit. When the switch is turned on, the electrical circuit is closed and, thus, complete. When the switch is turned off, the electrical circuit is open and, thus, incomplete. While all switches perform this operation, though, there are different types of switches, including mechanical and capacitive.
A capacitive switch is a type of touch-controlled electrical switch that operates by measuring change in capacitance. It works in the same manner as a typical capacitive smartphone: when you touch the surface — assuming you aren’t wearing gloves — a small electrical charge is transferred from your body to the switch, which subsequently causes a change in capacitance. The switch detects this change, responding with the appropriate command.

What’s the difference between an Alternate action and a Mometary?
The method that keeps the ON state of a switch only when its button is pressed and held is referred to as the “momentary” method, while the method that keeps the ON state of a switch even after the button is pressed and then released is referred to as the “alternate” method.
If you have ever had to research switches or even select a switch for a piece of electronic equipment, the number of switch technologies available on the market today might be a little overwhelming. This blog post will focus on two switches that look very similar but function according to completely different electronic principles. The question is: just what is the difference between a piezo switch and a capacitive touch switch?
