What is a Capacitive switch? and Advantages of Capacitive switch

Capacitive switches have gained a lot of popularity in recent years as an alternative to membrane switches, mechanical switches, elastomer keypads, and other input device options. With no mechanical parts to wear down, a slim profile that can be applied to curved surfaces, and intricate backlighting options, capacitive switches offer some exciting possibilities for your user interface. The Langir Electric started investing in the development of capacitive switch technology early in the interface’s inception. This has given our design engineers the experience to help you develop a world class solution for your product.

What Is a Touch Switch? What You Should Know

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.

What Is an Actuator in an Electrical 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.

5 Reasons to Choose a Capacitive Switch

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?

Capacitive vs Mechanical Switch: What’s the Difference?

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.

What is a Capacitive Switch and How Does it Work?

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.
