Abstract

In order to prevent accidental depression of a front panel power switch (12’) or front panel reset switch (14’) of a computer system (100), a novel circuit utilizing an additional safety switch (102’), the Safe-Lock switch, is proposed that provides a simple but effective way of preventing accidental switch closures without adding significant cost or complexity to the original switch functions.
