Hacking an output switch onto an ABRA AB-5300 Bench Power Supply. HELP!!

[SAR131]

I recently picked up electronics as a hobby.  I took Physics in high school many years ago and am enjoying this hobby.   I purchased a new ABRA AB-5300 Bench Power Supply from a company in Montreal Canada. It has 2 variable power outputs 30v 10a and a 5v fixed 3a power outlet.  At the time I did not realize the importance of an output switch to the leads.  Can I hack this device with output switches to the variable power outlets?   If so any recommendation on the particular switch preferably lighted when on.
 Appreciate any helpful advice!  Thanks,  SAR131
