Membrane switches are used to turn a circuit on and off. It is a type of electrical switch that is made up of a variety of materials including copper and plastic sheeting. Membrane switches also have a circuit printed on them.
What Is A Membrane Switch?
Membrane switches are generally made from five different layers. This includes membrane, graphic, tactile, rigid and static layers. The first layer contains the graphic interface for the user to control the machine. It can also include a flexible circuit for less expensive alternatives. Another layer will contain the printed circuit which allows a signal to be transmitted. The ink that is used for the printing on the circuit is generally made up of a variety of metals. This helps for the signal to be conductive for turning on and off. Membrane switches allow for communication to take place in electronic devices. Membrane switches are a piece of equipment that can be highly sophisticated or rather simple by design.
What Industries Use Membrane Switches?
Financial services, automotive and medical facilities all use membrane switches in a variety of different ways as part of their daily operations. Membrane switches are also employed in many large factories and warehouses in order to automate processes and switches. Some membrane switches are used to turn lighting on and off easily. Other types of switches are used a part of a computer controlled equipment. Membrane switches use back-lighting functions including light emitting diodes, optical fibers and electroluminescent lamps. Membrane switches are also used in many household appliances including microwaves, air conditioners and TV remotes. They are also used in conjunction with switch panels and other control systems including keyboards and touch-products. This technology can be found at banking machines, grocery check-outs and measurement devices.
Membrane switches allow a circuit to be turned on or off with very minimal effort. As technology advances so does the functionality and uses for membrane switches. They can now be used in outdoor settings, hazardous environments and in the dark.
