It is the standard interface of electronic building blocks and 2.54mm pin interface.
The cross rocker is a two-way 10K resistor. The resistance value of the tap changes with the direction of the rocker.
This module uses 5V power supply. Under the original state, the readout voltage of X and Y is about 2.5V.
When pressed along the direction of the arrow, the readout voltage value increases to 5V; When the arrow is pressed in the opposite direction, the readout voltage value decreases, and the smaller value is 0V.
It was made of high quality material, wear-resistant and durable.
