Water Heater By-Pass

There is the normal by-pass switch under the sink in the bedroom.
Had a leak on a connection on the rear of the heater and in fixing it,I discovered what is apparently another by-pass switch on the back of the unit. My owner's manual and other information items contain no information about this switch. The only way to get to this switch is to remove the drawers in front of the heater. What is the purpose of this switch?
