  • Spring-loaded contacts
    Patent number: 8905795
    Abstract: Spring-loaded contacts having an improved reliability. One example may provide spring-loaded contacts having a reduced likelihood of entanglement between a spring and a plunger. For example, a piston may be placed between a plunger and a spring. The piston may have a head portion that is wider than the diameter of the spring and located between the spring and the plunger to isolate the spring and the plunger. In these and other examples, an additional object, such as a sphere, may be placed between the plunger and spring. In another example, two additional objects, such as two spheres, may be placed between a plunger and piston.
