Abstract
An improved contact mechanism for a switch is disclosed in which impact between contacts is reduced or moderated to minimize rebound of the contacts thereby to prolong the life of the switch. The contacts are sufficiently spaced apart from each other when the switch is in a stable open position, but when the switch is operated, the movable contact is first moved gradually to an intermediate position toward the fixed contact whereafter it is moved rapidly to the fixed contact over a thus reduced distance.
