The utility model content

The purpose of this utility model, be to innovate a kind of general power button switch that is different from, so that be applicable in the circuit of particular surroundings work, the power button switch of a kind of mechanical type moment contact is provided, it is when inactive state, remain on the state of disconnection, its operation principle is: when implementing button operation with external force, the whole story in its moving process, all are the states that keep disconnection, only in moving process, the contact head is during by the certain position of the binding post under the switch shrapnel spare, and upper and lower contact could engage, but switch key continues when mobile forward again, then the contact head will be absorbed in the through hole of switch shrapnel spare, and this moment is because the tension force of spring becomes to making switch shrapnel spare to disconnect; When removing the external force operation, because of the spring tension of switch key outside, during with the outside resilience of switch key, be absorbed in the contact head of switch shrapnel, promptly rotatablely deviate from, during to the location again by the spring tension in the head of contact, recover the vertical position of head, original contact, so after can reaching control power supply moment contact conducting, the purpose of Duan Kaiing at once, specifically, be exactly manually to click switch key, power supply is the function that the moment conducting once promptly disconnects, and is simple in structure, with low cost, practical.

The technical solution of the utility model is, a kind of mains switch of machinery moment contact is provided, it is by loam cake, base, switch shrapnel spare, spring, switch key, the contact head, binding posts etc. are formed, loam cake is shaped by metal stamping, can tortuous clinching during assembling on housing, base inside is cavity body, the bottom is fixed with two binding posts, a binding post is provided with the contact, another binding post top card is equipped with switch shrapnel spare, switch shrapnel spare lower floor bottom one end is provided with corresponding contact, the handle portion of switch key is set with spring, and Spring Card is contained between housing and the spring card, and stretch out outside the shell in the hole of button handle from housing, the switch key inner end portion, be provided with cavity, be provided with groove below, the contact head is contained in the cavity of switch key rear end part, the fin of both sides is contained in the groove, one side fin be with a spring; Switch shrapnel spare levels is equipped with through hole.

The beneficial effects of the utility model are: can make the electromagnetic instant-touch type power supply switch work that can't start owing to stop using for a long time, and solve in the special circuit design, because of the element that can not switch on for a long time, for example powerful solenoid or electromagnetic switch etc., impaired even burn, and then influence the performance of its effect, and have certain problems such as potential safety hazard, simple in structure, practical.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Shown in accompanying drawing 1 and accompanying drawing 2, be the outside drawing of end view of the present utility model and front view.In end view, loam cake 1 is shaped by metal stamping, can tortuous clinching during assembling be fixed on housing and the bending stator as machinery panel, shown in front view.

As shown in Figure 3, shell of the present utility model bottom is chimeric two binding posts 11 are so that connect an end of power supply.

As accompanying drawing 4, shown in the accompanying drawing 5, be cut-away view of the present utility model and exploded view, it is by loam cake 1, drain pan 2, switch key 3, switch shrapnel spare 4, contact 5, spring 6, press key spring 7, institutes such as binding post 11 form, enclosure interior is a cavity body, the bottom is fixed with two binding posts 11, a binding post is provided with contact 10, another binding post top card is equipped with switch shrapnel spare 4, switch shrapnel spare 4 lower floors bottom one end is provided with corresponding contact 10, the handle portion of switch key 3 is set with by key spring 7, the button Spring Card is contained between housing and the spring card 8, the handle portion of switch key 3, stretch out outside the shell in hole from housing, and switch key 3 inner end portion are provided with cavity, be provided with groove 12 below, contact 5 is contained in the cavity of switch key 3 rear end parts, and the fin 13 of both sides is contained in the groove 12, one side fin 13 be with a spring 6; Switch shrapnel spare 4 levels are equipped with through hole 9, as shown in Figure 11.

Operation principle of the present utility model is, when staff directly acts on switch key 3, switch key 3 and contact 5 promptly is moved to the left, all are the states that keep disconnection, the whole story in its moving process only in moving process, when contact 5 during by the certain position of the binding post under the switch shrapnel spare 4, upper and lower contact 10 contacts because of the tension force of switch shrapnel spare 4, power turn-on, as shown in Figure 6; When switch key 3 continues when mobile forward again, then contact 5 will be absorbed in the through hole 9 of switch shrapnel spare 4, and this moment because the tension force of spring 6 becomes to making to disconnect on switch shrapnel spare 4 bullets, power supply disconnects, as shown in Figure 7; When removing the external force operation, the tension force of pressing key spring 7 because of switch key 3 outsides, during with the outside resilience of switch key 3, switch key 3 and contact 5 moves right, then be absorbed in the contact 5 of switch shrapnel spare 4 through holes 9, can clockwise direction rotate, as shown in Figure 8, when locating again by the tension force of spring 6, recover vertical position, original contact 5, so after can reaching control power supply moment contact conducting, the purpose of Duan Kaiing at once, specifically, be exactly manually to click switch key 3, power supply is the state that the moment conducting once promptly disconnects, solve in the special circuit design, because of the element that can not switch on for a long time impaired, even burn, for example powerful solenoid or electromagnetic switch etc., and then influence the performance of its effect, and have certain potential safety hazard.Simple in structure, with low cost, practical.The utility model can be directly installed on the place that people such as machinery panel can touch, and realizes the control to machine.
