Control switch for increased operational safety

Abstract

The invention discloses a control structure capable of improving the operating safety. 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 sinks inwards to form a clamping groove, the pressing button is provided with a limiting shaft, the limiting shaft is provided with a telescopic shaft, and a telescopic spring is connected with the telescopic shaft; 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 and 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 control structure, returning is achieved through springs arranged in a plurality of positions, the returning speed is high, the phenomenon that the control structure is struck is avoided, and an operator can use the control structure more safely.

Description

technical field [0001] The present invention relates to a switch, in particular to a control switch capable of increasing operational safety. Background technique [0002] A switch is an electronic component that can open a circuit, interrupt current, or cause it to flow to other circuits. Switching power supply is a 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 switching power supply and linear power supply, the cost of both increases with the increase of output power, but the growth rate of both is different. The cost of the linear power supply is higher than that of the switching power supply at a certain output power point, which is called the cost reversal point. With the development and innovation of power electronic technology, switching power supply technology is also constantly innovating, and this cost reversal point is increasingly moving to the low o...
