Push type aviation switch

Abstract

The invention relates to the field of switches, in particular to a push-type aviation switch. The push-type aviation switch comprises a push rod seat assembly, a pressing force conversion assembly anda microswitch assembly. The push rod seat assembly comprises a push rod, the push rod is connected to the pressing force conversion assembly, the microswitch assembly comprises at least three microswitches, wherein each microswitch is provided with a movable pin, a first fixed pin and a second fixed pin, a button seat is arranged between the pressing force conversion assembly and the microswitchassembly, a plurality of buttons are arranged on the button seat, the positions and the number of the buttons are in one-to-one correspondence with those of the movable pins, and the movable pins, thefirst fixed pins and the second fixed pins are all connected to power connection columns. In a noisy vibration environment, after an operator presses the switch, the operator can obviously sense whether the switch is pressed in place or not; the influence of the structure of a pressing reed on the service life of a reed is small, the requirement for the manufacturing process of the reed is not high, and the requirement can be met by adopting the reed on a common microswitch.

Description

technical field [0001] The invention relates to the field of switches, in particular to a push-type aviation switch. Background technique [0002] The aircraft is vibrated by airflow, engine and other factors, and it will also have impact when landing. Larger vibrations and shocks are not conducive to the normal operation of the switch, and even cause the contact of the switch to loosen, resulting in poor contact, which will cause a series of failures, and then affect the normal and safe flight of the aircraft. According to statistics, the switches of small aircraft often have poor contact due to vibration and shock, so it is urgent to improve the shock resistance and stability of the switch. [0003] The utility model with the authorized notification number CN207909776U proposes a high-performance aviation toggle switch. By setting a wavy reed, the ball in the lever device can stay stably in the curved contact part of the reed. Play a self-locking role, thereby improving ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned high-performance aviation toggle switch has three major deficiencies: 1. In a very noisy vibration environment, after the operator toggles the switch, the tactile feedback of the switch is poor, and the operator cannot perceive whether the switch is toggled in place; The requirements for capacity and service life are high, and the reed is required to be able to return to its original shape after deformation within a long service life. This undoubtedly puts forward higher requirements for the manufacturing process of the reed; Once damaged, the switch function will fail
