Abstract
The utility model relates to an electromagnetic safety switch, belonging to the switch connector of the domestic appliances. The electromagnetic safety switch is designed to overcome the problems that most of the general domestic appliances have mechanical switches and the waste or the fire hazard can be caused on the occasion of the electricity coming because the switches are forgotten to be turned off when the electricity fails. The electromagnetic safety switch comprises an electric magnet, a spring lamination, a normally open button, a normally close button, and a housing. The electromagnetic safety switch has the functions of energy saving and provided safety. The electromagnetic safety switch is popular after the mass use the electromagnetic safety switch.
Description
The utility model belongs to a kind of switch connector of household electrical appliance.
General household electrical appliance comprise that general lighting all is to adopt mechanical switch, when closing, send a telegram here again then that electrical equipment works on, the abnormal operation fire hazard of electric heating element when having a power failure, forgetting after the outage, office block has a power failure and to forget and turn off the light, and forms logical clouds illumination and causes very big loss.
The design's purpose is the safety switch that seals in an electromagnetic type in the circuit of household electrical appliance again, even be not related to electric switch after having a power failure, cutting off the power supply, restart when sending a telegram here again and could work, and can remove the hidden danger of fire like this, can also be energy-conservation, avoid waste.
By the safety electromagnetic switch that as above thinking provided, it is characterized in that it by electromagnet, elastic sheet metal, often open, normally closed button and shell form, its shell can be made of plastic, and its shape can be made rectangular box-like, also can make the pattern of three-way plug.
The structure of safety switch is that electromagnet coil is in parallel with electric appliance load, the spring leaf that suction is moved during with work of electromagnet seals the button of often opening that starts usefulness and works the effect of keeping, press the normally closed button of closing and make the electromagnet outage, spring leaf lifts, and stops the power supply to electrical appliance.After having a power failure or cutting off the power supply, electromagnet not working spring sheet lifts, and when sending a telegram here, be can not power to electrical appliance by start button no longer, so it has energy-conservation and safe effect again.
Present design embodies following advantage: have effect energy-conservation and assurance safety 1.; 2. simple in structure, be easy to make, cost is low; 3. easy to operate, noiseless, it is low to consume energy.
Description of drawings: Fig. 1 is the electrical schematic diagram of safety electromagnetic switch.Wherein: (1)-electromagnet (2)-elastic sheet metal; (3)-start button; (4)-X button; (5)-power input; (6)-power output end.
Embodiment: electromagnet core: adopt 08 steel, dimensions φ 8mm, long 20mm.Coil: wire size 42# copper cash φ 0.1mm, the number of turn is 5600 circles, appearance profile size: 40 * 40 * 84mm, about 100 grams of weight.
Claims (2)
1, a kind of safety switch of electromagnetic type, it is characterized in that it by an electromagnet, elastic sheet metal, often open button, normally closed button and shell and form, the normally closed button of its electromagnet coil and series connection is in parallel with load in circuit, it is often driven button and can go here and there in any line, the wiring of the wiring of its electromagnet coil and elastic sheet metal one end lays respectively at the both sides of often driving button, and elastic sheet metal should make during by adhesive often to be opened the button short circuit and play the maintenance effect.
2, according to the described safety electromagnetic switch of claim 1, it is characterized in that its shell can be made of plastic, its shape can make a rectangular box-like pattern that also can make three-way plug.
