Abstract
A precision switch and a switch blade/contact formed from uniform thickness sheet stock bent into U-shaped form wherein the edge surfaces after bending become the movable contacts of the high performance rugged tiny subminiature switch. The switch per se utilizes a configuration of pivotal rigid legs of the U-shaped blade/contact arranged to be spaced apart to maximum extent to allow a large diameter long coil spring located between the legs to be used for giving the blade/contact means precision high contact force operating characteristics which will withstand high G forces and will carry relatively large currents given the absolute size of the switch.
