Abstract: A solid dielectric deadfront electrical switch assembly having a switch contact assembly. The switch contact assembly can include an upper insulative diaphragm, a male pin contact having an insulating tip and an isolating sleeve, a primary contact, a lower insulative diaphragm, and a female socket contact. The upper insulative diaphragm, isolating sleeve, and insulating tip can assist in electrically isolating the male contact pin when the electrical switch assembly is in an open condition. Further, the upper insulative diaphragm can be separated from the female socket contact, and/or a female-contact insulating sleeve, by a gap chamber that utilizes air as an insulator. The lower insulative diaphragm can be configured to engage a drive rod that is used to axially displace the male pin contact between open and closed positions in a manner that may prevent arcing between the switch contact assembly and a base plate of a switchgear.

Abstract: A safety lockout device for switchgear includes a movable member adapted to be moved from a first position to a second position. A switch is adapted to electrically isolate a motor in the switchgear and a blocking arm is coupled to a shaft of the motor. In the first position, the movable member engages the switch to close the electrical motor circuit and the blocking arm is free to rotate with the motor shaft. In the second position, the movable member moves away from the switch so that the switch is in an open circuit state disconnecting power to the motor and a portion of the movable member is moved to a position whereby the blocking arm engages the movable member to prevent rotation of the motor shaft and a change of state of the switchgear. The position of the movable member relative to the switch provides a visual indication of the operating state of the switchgear.

Abstract: A status indicator includes a display disc with a pin located within a central portion if the display disc, a first colored section, and a second colored section. The status indicator also includes a lens unit with an opaque section and a non-opaque section to alternately reveal the first colored section or the second colored section such that either the first or the second colored section is visible from any angle within a hemisphere below the status indicator. The status indicator also includes an indicator cam configured to receive a linear force initiated by an actuator component and to translate the linear force to a rotational force on the pin. The rotational force causes the display disc to rotate from a first position to a second position that aligns the second colored section with the non-opaque section.

Abstract: A safety lockout device for switchgear includes a means for electrically disconnecting power to a motor and means for mechanically blocking the motor from operating. The safety lockout further includes a movable member operable by a hotstick to actuate the electrical disconnecting means and the mechanical blocking means.

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.
