Membrane Switch is an electrical switch with graphic overlay, logo , symbol display and spacer sealed together for turning a circuit on and off . Membrane switch typically comprises of four layers , top layer which is the graphic interface , upper circuit, spacer and lower circuit . For a light touch connectivity , membrane switches under normal conditions the upper and lower contact is disconnected but upon pressing the contact point between two traces would turn the circuit on . Conversely , when un-pressed , two traces are disconnected thus turn the circuit off.
A membrane switch structure ranges from simple to complex , good appearance , ease of cleaning , excellent sealing ability, humidity proof and highly durable . Membrane switches are widely used in multitude of products such as gaming consoles, communication devices, testing equipment, industrial controllers , medical equipment , automotive equipment , high end home appliances and many more.
Since membrane switch is water proof , dust proof, grease proof, protects erosion against harmful gases, proven reliable and longer life for decades , light in weight , flexible in size so make it easy to install . All graphic overlay are washable and scratch free , high degree of visibility , ability to be seen in a 180 degree radius. Truly an excellent option for user-equipment interface utilities that allow for the communication of commands from users to electronic devices. Membrane switches can be thought of as one category of interface utilities alongside touch screens, plastic keyboards, toggle switches and many other kinds of control systems.
