Touch sensors are more reliable and convenient with no moving parts. The two types are infrared which uses IR beams to detect when there is a touch and resistive that exhibits a decrease in resistance with an increase in force applied to the surface of the sensor. The output types are analog, I2C, and USB with a termination style of card edge/solder pad, connector, flex cable, solder tab, and tab.
