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, a kind of self-closing switch that has a power failure, have switch housing 11, circuit input end 1,2, circuit output end 9,10, between circuit input end 1,2 and circuit output end 9,10, be provided with power failure self closing circuit 13.Power failure self closing circuit 13, by resistance 3,4, dynamic circuit connector type relay 5, electromagnetic relay 6, electromagnetic switch K17 formed, circuit input end 1 connects conventional, electric-resistance 3,4 respectively as protective circuit resistance; Resistance 4 connects dynamic circuit connector type relay 5, resistance 3 connects a control end of dynamic circuit connector type relay 5, and another control end is connected 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 output 10.
Electromagnetic switch upper end is the shift knob 23 with handle 21 of turning off the light, and the inside is embedded with little iron block 22, and have the centre of two serial springs, 24, two springs to be provided with one piece of metallic plate 28 below, the two ends of metallic plate 28 are provided with two moving contacts 25; The bottom of two springs is provided with one piece of 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 the position of two metal connection posts 26,27 respectively, and can contact; Insulating base 29 is closely connected with the magnetisation end of electromagnetic relay 6.Two metal connection posts 26,27 are connected with switch wire 30 respectively.
As shown in Figure 4, a kind of self-closing desk lamp that has a power failure, comprises desk lamp shell 12, power for illumination bulb 8 and above-mentioned construction of switch.Between circuit output end 9,10, be connected to a lighting bulb 8, circuit input end 1,2 is connected to 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 (the present embodiment is bulb), press electromagnetic switch K17, spring in switch is depressed, four metal contact connect, dynamic circuit connector type relay 5 is energized, its control circuit is closure state, so the electromagnetic relay 6 in circuit and bulb energising, bulb is opened, the magnetic field that electromagnetic relay 6 produces can attract the little iron block in electromagnetic switch K17 button, and allow the circuit in the K1 that is pressed keep connection status, bulb lights;
When circuit input end disconnects, situation about namely having a power failure, electromagnetic relay 6 loses electric current, button on electromagnetic switch K17 is no longer by magnetic attraction, so by spring jack-up, the circuit in K1 is disconnected, and dynamic circuit connector type relay 5 is not when having electric current to pass through, the circuit controlling electromagnetic relay 6 and bulb is opened, bulb extinguishes, and K1 then returns to the state before being pressed, even if circuit input end closes again, the situation of namely sending a telegram here, bulb also can not light again;
When wanting normal shut-off circuit, gently draw the handle 21 of turning off the light of K1, dynamic circuit connector type relay 5 is not when having electric current to pass through, and the circuit controlling electromagnetic relay 6 and bulb is opened, K1 also can not be able to be attracted back because of the magnetic force losing electromagnetic relay 6, and bulb extinguishes.
