Function
The pedal functions by connecting the wires together when the pedal is depressed.

The wire consists of two conductors. One will be connected to the spring and the other connected to the metal wires at the end of the pedal.

This must adjust so that there is contact between the leaders when the pedal is pressed and the contact is broken when the pedal is released.
