Touch structure of micro switch

Abstract

The invention provides a touch control structure of a microswitch. A first accommodating chamber is formed on a body so as to respectively arrange two first conductive pieces, a first shaft rod and afirst spring and is fixed by a cover body, the two first conductive pieces are oppositely arranged in the first accommodating chamber in parallel, a through hole is formed in an appropriate position of one end, arranged in the first accommodating chamber, of each first conductive piece, the first shaft rod can sleeve between the through holes of the two first conductive pieces in a penetrating way, the first shaft rod has conductivity, the first spring sleeves the first shaft rod, one end of the first spring is in contact with one of the first conductive pieces, the other end of the first spring props against the first shaft rod and is in contact with the other first conductive piece, the state that a power supply is conducted is shown, the first spring is separated from one of the first conductive piece when a strut part at an outer side of the first shaft rod is pushed by an external force, so that the power supply or a signal is disconnected, and the assembly convenience and the acting stability of the microswitch are improved.

Description

technical field [0001] The invention relates to a power control switch, in particular to a control structure for controlling the power on and off by touch. Background technique [0002] Press, general reciprocating transmission machines need to use electronic signals to start or close the transmission control, and the transmission control of electronic signals is mostly achieved by using micro switches. For example, the transmission stroke of a linear actuator is tied between the starting point and the end point. The position uses the micro switch as the control of the forward and return strokes of the linear stroke. It can be seen from the background technology that a micro switch structure system for controlling the power supply on-off signal is as follows: Figure 15 As shown, the prior art is provided with a shaft 7, a spring 6, and first and second conductive strips 14, 15 in the housing portion 2 of a body 1; the shaft 7 has no conductivity, and one end passes outward ...

AI Technical Summary

Problems solved by technology

[0003] When the above prior art is used, because the conductive part 16 of the first guide piece 14 is only in contact with the pressure plate 8 by its own gravity, and is in point contact, if vibration or shaking occurs, there will be poor signal transmission , and after long-term use, there will be poor contact. Furthermore, the existing case is inconvenient to assemble, and can only be used for single electronic signal control, and cannot achieve dual-signal micro-control
