How to get +5V to -5V??

As the OP hasn't even told us how many (milli)Amperes he needs from the -5V, it might not even be practical for a 555 charge pump solution. Though given what little we have to go on, I would agree this is the most likely answers for now.
 

In my view you can generate both +5v and -5V from center-tap transformer approach and use relay's NC contact for +5Volt NO for -5V and common as a control signal going to your circuit......and control the relay coil for getting either voltages ..... In the Opamp Circuit you need to have +/- 5volt supply any how..... and in Charge Pump Circuit dose not allow you to drive the load more than 50ma......

Good Luck
 

Reverse the wires to get -5 volts. Or use a MAX1044.
