I don't know why 4 wires are connected, it depends on how it was wired...

You could use a DPDT momentary switch, with the center position being the default, wired like this:
Power | x
Power | | Reset
x | Reset
Basically you take the two wires for the power button, and connect it to the two pins on the upper left (the |), and you connect the two wires for the reset button to the two pins on the lower right.
The upper right and lower left pins (the x) are not connected.
With a center-operating momentary DPDT switch, the switch stays in the middle during normal operation - eg, normally open.
Flick the switch up, and you toggle the power button.
Flick it down, and you toggle the reset button.
A DPDT Center Off Momentary switch like this would do it:
However, it may be a bit large, being that it's designed to carry 20 amps worth of current.
One of the mini DPDT switches would do fine, if you can find a center off momentary version.
