Abstract

A progressively contacting switch includes a set of contacts connected to an input. The set includes a first sacrificial contact formed of a first metal and a first conducting contact formed of a second metal. The switch further includes a movable set of contacts connected to an output. The movable set includes a second sacrificial contact formed of the first metal and a second conducting contact formed of the second metal. The switch includes an element configurable to connect the movable set of contacts such that the first sacrificial contact connects to the second sacrificial contact at a first time, thereby causing a current to flow from the input to the output, and while the first sacrificial contact remains connected to the second sacrificial contact, the first conducting contact connects with the second conducting contact at a later time.
