Well i got it from china but no instructions so any ideas on how to wire it up please

The key has 2 switches,so i think that i could if needed use it for 2 different devices,but i only want to turn pump off and on.
This is the lay out of the terminals
DC 12V + -
NO2
COM2
NO2
NO1
COM1
NC1 (is this one a miss print,i thought NO1 ??)
Thanks for any help with this.
