Automatic control switch

Abstract

The invention belongs to the technical field of a control switch and in particular relates to an automatic control switch. The automatic control switch comprises a switch body; one side surface of theswitch body is provided with a fixing groove; an outer shell of the switch body comprises a steel plate, an insulating rubber plate, a fire extinguishing layer and a plastic shell; the steel plate isdisposed at an interior of the outer shell; two side surfaces of the steel plate are provided with the insulating rubber plate; and one side surface, different from the steel plate, of the insulatingrubber plate is provided with the fire extinguishing layer. According to the automatic control switch, by use of the insulating rubber plate, the excessively high external temperature is prevented from being conducted to the interior of the switch body; when a fire disaster breaks out at the interior or exterior of the switch body, the plastic shell is burned and broken, fire-extinguishing dry powder is ejected from the interior of a mesh skeleton at this time to distinguish the fire disaster; the steel plate plays the role of strengthening a sealing structure of the switch body, thereby preventing mutual interference between the environment at the interior of the switch body and the environment at the exterior of the switch body and improving the stability of the automatic control switchduring use.

Description

technical field [0001] The invention belongs to the technical field of control switches, and in particular relates to an automatic control switch. Background technique [0002] The control switch is a special switch used in the process control of electrical control and thermal instruments. Some problems are still exposed in the use of the current control switch. When the control switch is used, it is greatly affected by the outside world. In the event of a fire, the control switch will be damaged, and the control switch cannot operate well. In view of the problems exposed during the use of the current control switch, it is necessary to improve and optimize the structure of the control switch. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides an automatic control switch, which has the characteristics of improving the operation stability of the switch. [0004] In order to achieve the above obj...
