Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0014] see figure 1 , the present invention includes a control loop composed of a step-down rectifier module and an electromagnetic relay, and an action loop controlled by a ship-type double-control switch, wherein the ship-type double-control switch controls whether the electromagnetic relay in the control loop is energized, and the electromagnetic relay controls the action loop Whether the ship-type dual-control switch and its own control terminal are energized, the ship-type dual-control switch controls

[0015] Whether the electrical equipment is powered on. The input terminal of the step-down rectification module 2 is connected to the output of the ON terminal 3 of the ship-type switch, the output terminal of the step-down rectification module 2 is connected to the contact point 9 of the electromagnetic relay, the contact point 6 of the electromagnetic relay...

Abstract

The invention belongs to the field of basic electrical apparatus element electric switches, and particularly relates to an energy-saving electromagnetic switch. The energy-saving electromagnetic switch comprises a control loop consisting of a step-down rectifying module and an electromagnetic relay, and an acting loop controlled by a rocker double control switch, wherein an input end of the step-down rectifying module is connected with an output of an ON end of the rocker switch; an output end of the step-down rectifying module is connected with an electromagnetic relay contact; the electromagnetic relay contact is grounded; the electromagnetic relay contact is connected with an input of the ON end of the rocker switch; the electromagnetic relay contact is connected with an input of an ON / OFF end of the rocker switch; and an output of the ON / OFF end of the rocker switch is grounded through electric equipment. The energy-saving electromagnetic switch is based on an electromagnetic induction principle; a circuit of the electric equipment can be cut off automatically when a main power supply is disconnected; and the electric equipment can still keep in a disconnected state when the main power supply is connected once again. The energy-saving electromagnetic switch has great significance to power saving and energy saving in present school classrooms.

Description

technical field [0001] The invention belongs to the field of electric switches of basic electrical components, and in particular relates to an energy-saving electromagnetic switch. Background technique [0002] At present, in the vast majority of schools, especially middle schools and universities, when students leave the classroom for evening self-study, the school cuts off the power supply of the classroom lighting and other electrical equipment by cutting off the main power supply of the teaching building, and then restarts the next morning. Turn on the mains to power all classrooms. But when the classroom was powered on the second day, the switch of each electrical device was not disconnected on the first night, so the electrical device was still consuming electricity when the classroom was empty the next morning. This causes waste of electric energy. Therefore research and develop a kind of switch that can automatically cut off electrical equipment and circuit after t...
