Problems solved by technology
[0003] The purpose of the present invention is to overcome the problems that the switch is often stuck or the distance of the switch is not easy to grasp, the precision control of the large computer cannot be realized, and the internal components are easily damaged. The switch, which uses the set spiral groove to realize the control of the opening and closing stroke of the computer, realizes precise control of the computer, prevents the damage of its internal components, and solves the problem that the switch is often stuck or the distance of the switch is not easy to press. Grasp, can not achieve precise control of large computers, easy to cause damage to internal components

The invention discloses a switch capable of performing accurate control. A through hole is formed in a shell, a limiting convex block is arranged in a cavity, a pressing button is fixed to the limiting convex block and penetrates through the through hole, the through hole sinks inwards to form a strip-shaped groove, the strip-shaped groove is a spiral groove, the strip-shaped groove is communicated with the interior of the cavity, the pressing button is provided with a limiting shaft, the limiting shaft is fixed to the pressing button, and the limiting shaft makes contact with the strip-shaped groove; the limiting convex block is provided with a main spring, the main spring is connected with the limiting convex block and the cavity, the limiting convex block is provided with a connecting rod, the connecting rod is fixed to the limiting convex block, the connecting rod is provided with a rotating shaft, the rotating shaft is fixed to the shell, the connecting rod is provided with a metal contact ball, a normally-open contact and a normally-closed contact are arranged in the cavity, and the metal contact ball is arranged between the normally-open contact and the normally-closed contact. According to the switch, the starting and stopping process of a computer is controlled through the arranged spiral groove, the computer can be accurately controlled, and internal elements of the computer are prevented from being damaged.
Description
technical field [0001] The invention relates to a switch, in particular to a switch capable of realizing precise control. Background technique [0002] A switch is an electronic component that can open a circuit, interrupt the current flow, or allow it to flow to other circuits. Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Compared with the linear power supply, the cost of the switching power supply increases with the increase of the output power, but the growth rate of the two is different. At a certain output power point, the cost of linear power supply is higher than that of switching power supply, which is called the cost reversal point. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. This cost reversal point is increasingly moving to the low output p...
