The keycap connector and spring work together to attach the keycap to the spring assembly and push the keys to the upwards position once pressed down. Additionally the red key connector pushes against the larger electrical pin which opens the electrical circuit, sending a signal to the circuit board that the key has been pressed.

The keycap connector is injection moulded red ABS. The spring is thinly extruded and coiled steel. Finally, the pins are stamped, pressed, and bent from copper sheet. These components all fit within the spring housing.
