What Special Features Can Be Incorporated into Membrane Switches?
Tactile Feedback
Membrane switches can be manufactured with non-tactile switches, which activate with 4 – 8 oz of touch pressure. Non-tactile switches are less expensive and provide the longest switch life. Tactile switches have a snap-action feel and may also be incorporated into a membrane switch, enhancing tactile feedback, but with a greater cost and lower switch life.
Lighting Options
There are three standard methods for illuminating membrane switches.
Light Emitting Diodes (LEDs) are a popular, low-cost, point-source lighting method to back light membrane switches. LED’s emit very little heat, and come in a variety of colors, lamp packages, and intensity levels. LED’s are used as indicator lights and are not designed for overall back lighting of a panel.
A second option is optical fibers. Fiber optic lamps are an effective method to achieve more uniform back lighting across a broader area of the membrane switch keypad. With fiber optic back lighting, light from a light source, normally an LED, is evenly distributed under the graphics by use of very thin plastic fibers. Optical fibers are not affected by extremes in humidity (0% to 100%) or temperature (-40 to +85 deg C).
The third option is electroluminescent (EL) lamps. They are lower priced compared to optical fibers and offer additional design flexibility. EL lamps are best suited for applications where the back light is a minimum requirement, because the phosphors tend to decay with extended use at high voltages and frequencies. Thus EL lamps are not a good choice if the lamp is on for an extended period of time.
