A disconnect switch generally has an external handle which is manually operated to break the connection between the power source and the electrical system. There are two types of power disconnect switches, a temporary disconnect switch and a permanent disconnect switch. The temporary disconnect switch has a relatively safe means for opening and closing the switch while preventing human contact therewith. The permanent disconnect switches are often mounted on a metal plate. The permanent disconnect switches have two conductors secured by screws going through a base of the switch. Disconnect switches are frequently used to switch transformer magnetizing current, low level line or cable charging current, and parallel load currents. Medium duty power disconnect switches are used in power generation, power distribution systems and power transmission. A battery disconnect switch is a bidirectional switch that is used for enabling or disabling a current flow between a battery and a load or a battery and a battery charger. AC disconnect switches are often used for connecting AC current to and disconnecting AC current from air-conditioner compressors. AC disconnect switches operate between on and off conditions by inserting a pullout handle assembly into and removing the pullout handle assembly from a stationary terminal block assembly mounted within the enclosure of the AC disconnect switch. Electrical disconnects typically comprise a disconnect switch assembly and related connecting equipment, such as lugs and ground terminals, housed within a disconnect enclosure. A manual electrical disconnects are located near electrical equipment such as motors, compressors, motor controls or other electrically driven machinery.
