With an extensive range of Push Button, Vandal Resistant, Piezo, Slide, Toggle and Rocker switches available, Langir’s switch range is designed to meet the design requirements of a wide variety of industry applications ranging from medical and industrial to marine and commercial electronics.
Langir’s head engineer discusses the differences between the rear panel mount and the front panel mount switches.
Available with diameter from 16 to 25mm bushing, CP series sensory switches are extremely easy to use and ideal for repetitive applications (no operating force). Their IK10 robustness and unlimited life are perfect for self-service applications.
The L19S and L22S provides a unique aesthetic feature of a 25mm square bezel over the standard round bezel. The panel cut-out size is 19mm and 22mm diameter and it provides IP65 rating for dust and moisture protection. It offers multiple options such as ring illumination, 1NO1NC or 2NO2NC circuits, stainless steel housing material, and many LED color options which also includes an RGB LED option. The switch is also available in either a momentary or a latching function and can also be supplied with laser etched power symbol. There is also the option to add wire leads for your convenience.
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.
