I am trying to use the circuit diagramed in the associated schematic as the source of power in a project I am building, but am apparently missing something obvious. It provides +5V when the switch is depressed, but the -5V is always on regardless of the switch position. I have checked and rechecked, and don?t believe I have anything hooked up incorrectly. Have also replaced the 7905, without effect. If no one can find anything wrong with the provided schematic, I am back to square one, and will simply disassemble and reassemble from scratch to see if that provides any results. The basic idea for this schematic came from the 7905 datasheet.
PS: schematic posted to ABSE under title "+/-5V schematic".
