Problems solved by technology

The momentary push switch generally presses the button with the finger, and the micro switch is switched through the general transmission part or the snap-action mechanism. When the finger leaves, the mechanism recovers and the circuit switches back to the initial state; the push switch with the mechanical hold function can maintain the switch state after being pressed, But you still need to press to unlock when unlocking

Embodiment Construction

[0027] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other. See Figures 1 to 5 , what is shown in the figure is a push switch with magnetic holding function, which is used for the state switching switch of the aircraft operating mechanism. The push switch is mainly composed of a switch housing, a pressing component 1, an electromagnetic component 2, a micro switch 3 and a switch snap component 4 and other components.

[0028] The switch housing is composed of a shell and a switch bracket. The casing is used to accomm...

Abstract

The invention discloses a pressing switch with a magnetic latching function and a using method of the pressing switch. The pressing switch comprises a pressing assembly, an electromagnetic assembly and a microswitch, wherein the pressing assembly is composed of a button part and a pressing longitudinal shaft; the electromagnetic assembly is composed of a fixed coil, a movable iron core, a fixed iron core and a reset spring, wherein a guide hole channel extending along the longitudinal direction is formed in the fixed coil; the movable iron core is movably combined in the guide hole channel; the fixed iron core is fixedly combined in the guide hole channel, and the fixed iron core is positioned below the movable iron core; and the microswitch is located below the electromagnetic assembly, wherein a switch contact is arranged on the top surface of the microswitch. The pressing switch has the following beneficial effects that the pressing latching function is completed by a magnetic latching mechanism, the operation process is simple and reliable, and the switch function is effectively improved.

Description

technical field [0001] The invention relates to a push switch with a magnetic holding function and a use method thereof. Background technique [0002] The push switch is a state switching switch used to control the control mechanisms of the aircraft. The momentary push switch generally presses the button with the finger, and the micro switch is switched through the general transmission part or the snap-action mechanism. When the finger leaves, the mechanism recovers and the circuit switches back to the initial state; the push switch with the mechanical hold function can maintain the switch state after being pressed, But you still need to press to unlock when unlocking. Therefore urgently need to improve existing press switch state maintenance mode. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic switch that can improve the holding function of the push switch, so that the switch can be held when it is...
