Underneath the Superstrike: How Logitech kick-started next-gen mouse tech

The Logitech G Pro X2 Superstrike introduces analogue technology to gaming mice that allows adjustable actuation and a rapid trigger. You can set the left or right click to register with very little pressure and to re-register almost immediately on release. The result is drastically less click latency, the time between starting a press and the in-game response.

Instead of a Hall effect sensor, the Superstrike uses electromagnetic induction. A coil on the PCB generates a magnetic field while a thin metal trigger plate moves through that field; the disturbance is measured to determine position. Under each key plate there is a linear resonant actuator, a trigger plate, and an inductive sensor, and when the plate crosses the actuation point the PCB fires the LRA to produce the click feeling.

Haptics were part of the design from the start. Logitech calls the system HITS, for haptic inductive trigger system, and engineers found prototypes without haptics were not usable because players need tactile confirmation.
