ABSTRACT:
A micro-switch has an auxiliary return spring in the form of a hairpin spring acting directly on the actuating button through a hole in the contact carrier to increase the return force on whatever external means engage the button, but without affecting the behavior of the contact carrier. The use of a hairpin spring allows it to be accommodated within an existing standard switch body without upsetting the placing of standard mounting holes.
