Abstract
The invention discloses a novel single-button power failure self-closing switch and a table lamp with the novel single-button power failure self-closing switch. The power failure self-closing switch is provided with a switch outer shell, two circuit input ends and two circuit output ends. A power failure self-closing circuit is arranged among the circuit input ends and the circuit output ends. The power failure self-closing circuit comprises a resistor R1, a resistor R2, a normally-opened-type relay, an electromagnetic relay and an electromagnetic switch K1. Under the condition with the requirement for lighting, the electromagnetic switch K1 is pressed down, and the table lamp is turned on. Under the power failure condition, the electromagnetic switch K1 will automatically bounce up, and the circuit is opened. Under the condition with the requirement for normal closing, a lamp-closing handle on the electromagnetic switch K1 is just required to be lightly pulled up. Compared with an existing lighting switch which is forgotten to be closed after power failure, the novel single-button power failure self-closing switch can automatically shut off the circuit due to the specific electromagnetic switch in case that the lamp lights the place without the requirement for the lighting after power is on, and energy sources are saved. Compared with lighting switches of the same kind, the novel single-button power failure self-closing switch has the advantages of being simple in structure, low in manufacturing cost, convenient to install, capable of being operated by a single button and the like.

Embodiment
As shown in Figure 1, 2, 3, the self-closing switch of a kind of power failure has switch housing 11, circuit input end 1,2, circuit output end 9,10, circuit input end 1,2 and circuit output end 9,10 between be provided with power failure self closing circuit 13.Power failure self closing circuit 13 is made up of resistance 3,4, moving mould assembly relay 5, electromagnetic relay 6, electromagnetic switch K17, and circuit input end 1 connects conventional, electric-resistance 3,4 respectively as protective circuit resistance; Resistance 4 connects mould assembly relay 5, resistance 3 connects a control end of mould assembly relay 5, and another control end links to each other with electromagnetic relay 6, another termination output 9 of electromagnetic relay 6, electromagnetic switch K17 one end interlock mould assembly relay 5, one end connection circuit outputs 10.
The electromagnetic switch upper end is for having the shift knob 23 of the handle 21 of turning off the light, and the inside is embedded with little iron block 22, has the centre of 24, two springs of two serial springs to be provided with a metallic plate 28 below, and the two ends of metallic plate 28 are provided with two moving contacts 25; The bottom of two springs is provided with an insulating base 29, and the two ends of insulating base 29 are provided with two metal connection posts 26,27.Two moving contacts 25 are relative with two metal connection posts 26,27 position respectively, and can contact; Insulating base 29 closely links to each other with the magnetisation end of electromagnetic relay 6.Two metal connection posts 26,27 link to each other with switch wire 30 respectively.
As shown in Figure 4, the self-closing desk lamp of a kind of power failure comprises desk lamp shell 12, power for illumination bulb 8 and above-mentioned construction of switch.Connected a lighting bulb 8 between circuit output end 9,10, circuit input end 1,2 has connected a 220V standard plug 14.
The operation principle of power failure self closing circuit 13 is: when circuit input end 1,2 connects power supply, circuit output end 9,10 connects load (present embodiment is bulb), press electromagnetic switch K17, spring in the switch is depressed, four metals get an electric shock and join, moving mould assembly relay 5 energisings, its control circuit is closure state, so the electromagnetic relay 6 in the circuit and bulb energising, bulb is opened, the magnetic field that electromagnetic relay 6 produces can attract the little iron block in the electromagnetic switch K17 button, allows the circuit among the K1 that is pressed keep connection status, and bulb lights;
When circuit input end disconnects, i.e. the situation of Ting Dianing, electromagnetic relay 6 loses electric current, button on the electromagnetic switch K17 no longer is subjected to magnetic attraction, so by spring jack-up, the circuit among the K1 is disconnected, moving mould assembly relay 5 is under the situation that does not have electric current to pass through, the circuit of control electromagnetic relay 6 and bulb is opened, bulb extinguishes, and the state before K1 then returns to and is pressed is even circuit input end is closed again, i.e. Lai Dian situation, bulb can not light again yet;
When wanting normal shut-off circuit, gently draw the handle 21 of turning off the light of K1, moving mould assembly relay 5 is under the situation that does not have electric current to pass through, and the circuit of control electromagnetic relay 6 and bulb is opened, K1 also can or not be attracted back because of the magnetic force that loses electromagnetic relay 6, and bulb extinguishes.
