Abstract
An electrical switch which includes an insulative housing having a wall defining an axial bore therein, a first electrical contact disposed in the housing bore and a second electrical contact movably disposed in the housing bore between an open position and a closed position. When the contacts are in their open position, the second electrical contact is spaced apart from the first electrical contact and when the contacts are in their closed position, the second electrical contact is in electrical contact with the first electrical contact. The switch includes features to enhance safety and operation by reducing the possibility of arcing or flashover before and during the switching operation and to provide of visual indication of the state of the switch.
