Sadly my the switch on my ALO Rx amp snapped off. I've opened the amp up and found the switch it uses but I am not entirely sure if it is the correct on as I do not have much knowledge with electronic components. 
 
I am thinking it is this switch http://search.digikey.com/scripts/DkSearch/dksus.dll?pname?site=au;lang=en;name=EG4909-ND because it looks identical. I have narrowed it down that it is a DPDT switch as the switch has 6 pins but not sure if the ON-ON variant is correct. 
 
 
Here are the images of the original switch
