PERSONAL COMPUTER POWER SUPPLY ON-OFF SWITCH ACTIVATOR COMPLIANT.

This article describes a mechanism which provides alignment, adjustment, and synchronization for positive on-off switch action during testing of a personal computer (PC). In system testing of PCs it is necessary to provide positive on-off switch action of the power supply during test. Conventionally, a PC arrives at a test station via a plastic pallet carrier. A test head assembly is activated and moves forward to engage with the back of the PC chassis. Several compliants of different types are sequentially activated to provide specific test functions. Since accumulated tolerances of the pallet carrier and the PC vary, it is important that the switch on-off compliant is accurately aligned to the power supply switch, providing positive on-off action, as required. The compliant should be self-aligning to adjust to the pallet carrier and product dimensional changes. Such a mechanism is presented.
