A waterproof magnetic switch with electric leakage alarm

Abstract

The invention relates to a waterproof type magnetic control switch with electric leakage alarm. The waterproof type magnetic control switch with electric leakage alarm comprises a switch main body, adisplay lamp and a magnet coil, wherein a middle end of the switch main body is provided with a rectangular frame body, and a link-up plate is fixed right above the rectangular frame body, the displaylamp is arranged at a left side of the rectangular frame body, an interruption clapboard is fixed at an internal middle end of the switch main body, a first point contact block is mounted above the isolation plate, a second point contact block is connected under the interruption clapboard, the magnet coil is arranged at the right side of the inside of the switch main body, and an electric leakagesensor is arranged at a lower right corner of the magnet coil. The waterproof type magnetic control switch with electric leakage alarm provided by the invention has the following beneficial effects:with arrangement of the electric leakage sensor and a buzzer alarm, the waterproof type magnetic control switch has an electric leakage alarm function, when the inside of the switch main body generates an electric leakage phenomenon, the electric leakage sensor under cooperation with a controller enables the buzzer alarm to perform an alarm work, thus, workers are helped to discover the electric leakage phenomenon in time.

Description

technical field [0001] The invention relates to the technical field of magnetic switches, in particular to a waterproof magnetic switch with an electric leakage alarm. Background technique [0002] The magnetic control switch is a line switching device controlled by a magnetic field signal. The commonly used magnetic control switch has two types: single contact and double contact. Wait, the switch is the dry reed switch. The dry reed switch is the abbreviation of the dry reed switch. It is a passive electronic switch element with contacts. It has the advantages of simple structure, small size and easy control. Its shell is generally a A sealed glass tube with two iron elastic reed electric plates filled with inert gas. Normally, the two reeds made of special materials in the glass tube are separated. When there is magnetic When the substance is close to the glass tube, under the action of the magnetic force lines of the magnetic field, the two reeds in the tube are magnetiz...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a waterproof magnetic switch with electric leakage alarm to solve the problem that the structure of the existing magnetic switch proposed in the above-mentioned background technology is relatively simple, and it is necessary to use a single-touch Point and double contacts work, resulting in a waste of resources. At the same time, because the general magnetic switch is exposed in the air, dust is extremely easy to stick to the contacts, which is not convenient for the normal use of the staff.
