1. A switchgear, comprising: a housing;a plurality of fuses mounted within the housing, each fuse having a striker pin that is ejected from the fuse when the fuse is operated;a plurality of fuse operation indicator assemblies mounted within the housing, one for each fuse, the fuse operation indicator assembly comprising: an electrically insulating elongate tube having first and second ends;a fuse striker receiving member at the first end of the tube, wherein the fuse striker receiving member receives the fuse striker pin when it is ejected from the fuse, and wherein the fuse striker receiving member comprises a spring-loaded piston that generates a puff of air through the tube when the fuse striker receiving member receives the fuse striker pin; andan electric switch comprising a switch actuator spaced apart from the second end of the tube, wherein the switch actuator is actuated by the puff of air generated by the spring-loaded piston;wherein the electric switch and the fuse are mounted in the housing in a spaced-apart relationship. 2. The switchgear of claim 1, wherein the electric switch generates an electrical signal when the switch actuator is actuated by the puff of air. 3. The switchgear of claim 2, wherein the fuse indicator assembly comprises a mounting block mounted in the housing, and wherein: the electric switch is mounted on the mounting block; andthe second end of the tube is held adjacent the electric switch by a clamping device that is mounted to the mounting block. 4. The switchgear of claim 2, further comprising a plurality of indicators outside the housing, each indicator electrically connected with a respective electric switch, wherein each indicator receives the electrical signal and, in response, indicates that the fuse is operated. 5. The switchgear of claim 2, further comprising a controller and a display, the display being outside the housing, the controller electrically connected with each switch of the plurality of fuse operation indicator assemblies, wherein the controller receives the electrical signals from the switches and controls the display to display identifying information associated with the electrical signals. 6. The switchgear of claim 5, wherein the identifying information includes an identification and/or location of one or more fuses that have operated. 7. The switchgear of claim 2, further comprising a controller and a transceiver, the controller electrically connected with each switch of the plurality of fuse operation indicator assemblies, wherein the controller receives the electrical signals from the switches and controls the transceiver to wirelessly transmit identifying information associated with the electrical signals to an outside device. 8. The switchgear of claim 7, wherein the identifying information includes an identification and/or location of one or more fuses that have operated. 9. The switchgear of claim 1, further comprising an actuating member movably disposed at the second end of the tube and spaced apart from the switch actuator, wherein the puff of air generated by the spring-loaded piston causes the actuating member to move and contact the switch. 10. The switchgear of claim 1, further comprising an actuating member at the second end of the tube and spaced apart from the switch actuator, the actuating member comprising an orifice through which the puff of air is emitted to actuate the switch actuator. 11. The switchgear of claim 3, further comprising a deformable pad between the mounting block and the second end of the tube.
