Manual shift switch

Abstract

The invention discloses a manual shift switch comprising a bakelite plate, large insulating bases, a substrate and a handle base. A plurality of large insulating bases are arranged between the bakelite plate and the substrate, and the handle base is arranged at the bottom of the substrate. The manual shift switch is characterized in that a plurality of fixed copper plates are fixed at the rear ofthe upper part of the bakelite plate, grooved copper plates which are the same as the fixed copper plates in number are arranged in the front of the upper part of the bakelite plate, lining plates and water-cooled copper plates are arranged between the fixed copper plates and the grooved copper plates, one end of the handle base is provided with a handle, the handle is connected with a handle shaft which is arranged in the handle base, one end of a connecting rod is connected with the handle shaft, the other end of the connecting rod is connected with a pin shaft, the pin shaft can be provided with one antirust flat plate or two antirust flat plates on one end or two ends, the one antirust flat plate or two antirust flat plates can rotate around the pin shaft, and two sides of a small insulating base are respectively and fixedly connected with an antirust flat plate and a lining plate. The invention solves the problems that the power supply of the high-power switch has poor radiating performance and the high-power switch has complex and incompact structure. The manual shift switch has simple structure, good insulating performance, strong radiating effect and low manufacturing and operating cost.

Description

technical field [0001] The invention relates to a switch used in the electrical field, in particular to a manual alternate switch. Background technique [0002] At present, all high-power switching power supplies must solve the cooling problem of the heat generated by power devices due to loss during the inverter and rectification process, so as to ensure that the power devices work in an allowable temperature environment. When used in various mechanical equipment, if effective heat dissipation cannot be carried out, the service life of high-power power switches will be seriously affected, and even large mechanical equipment cannot work normally, which will bring great inconvenience to users. At present, most of the cooling of the high-power power switch housing is done by ventilation, including natural air cooling and forced air cooling: [0003] 1) Natural air cooling: transfer the heat of the power device to the copper or aluminum radiator, and use the convection of the ...
