This IR proximity contactless button makes for a good replacement for typical push buttons in situations where touching the button isn't required or desirable. This button includes a built in microcontroller to handle interference or noise, a red/blue status LED gives the user visual feedback that a "touch" has been registered, and two potentiometers on the back of the device allow you to adjust the read range from 3-15cm and adjust the "open time" from 0.5 to 20 seconds.
All this is encased in an durable package that easily mounts through most panels and surfaces.
More information is available in the datasheet.
