Light Strike optical switches utilize a horizontal infrared beam which is transmitted across the width of the inner keyswitch.9,The infrared beam is normally blocked from reaching a sensor across from it by the stem. Once a switch is pressed, the switch stem no longer blocks the infrared beam and the beam is detected by the sensor, which activates the switch.10,Due to the optical mechanism, an optical switch has an extremely fast response for time of 0.2ms, which means faster reactions in those times where timing is critical, such as when gaming.
