Contacts, Spring Loaded (Pogo Pins), and Pressure

Spring-loaded contacts, also known as "pogo pins" in reference to the toy they resemble, are commonly used to establish electrical contact between two objects whose relative mechanical position cannot be well-controlled, or a connector system tolerant of frequent mating/unmating cycles is desirable. Charging cradles for cordless handheld devices such as bar code scanners and mobile radios are a common example. Contact pads used to create a durable, corrosion-resistant surface for spring-loaded contacts to bear against are also included within this product family.
