what is the 5v pin next to the switch pins for?

Hi @catdog -
That pin could supply 5V to whatever needs it! The SWITCH signal (center) pin must be connected to ground (GND pin) by a switch or jumper for the motors to turn. The 5V pin provides a point to check that the unit is receiving sufficient voltage, or to power a low-demand 5V device like an LED.
