Description

Three-position self-reset toggle switch

Technical Field

The invention relates to the technical field of switches, in particular to a three-position self-resetting toggle switch.

Background

The toggle switch is generally used on an airplane steering column, a pilot controls a circuit on a machine, the influence of self vibration in the airplane flying process is received, the pilot judges whether the switch operation is in place mainly by the in-place feedback or flight control display of the switch, and the conventional double-pole double-throw three-position toggle switch cannot provide the pilot with in-place hand feeling by sliding a steel ball in a push button on an inclined plane of a shell, so that the condition that the pilot is not enough in operation stroke and cannot be reliably connected often occurs, and even a cap is pushed out of the switch shell.

Disclosure of Invention

The invention aims to overcome the defects and provide the three-position self-resetting toggle switch which not only has good in-place hand feeling of the three-position two-side locking toggle switch, but also realizes the self-resetting function.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention discloses a three-position self-resetting toggle switch which is characterized in that a switch body is arranged on the switch body; the base is respectively inserted with the static contact piece and the movable contact piece, the base is clamped into the lower end of the shell, the outer surface of the shell is sleeved with the gasket and screwed with the nut, the push button is respectively placed in the reset spring, the snap spring and the steel ball to be clamped into the upper end of the shell, the top end of the movable contact piece penetrates through the shell to be inserted into the push button, and the two reset springs respectively abut against the raised heads arranged at the top end of the base.

The two ends of the snap spring are respectively provided with steel balls, and the two steel balls are respectively clamped in grooves respectively arranged at the two ends of the shell.

The push button can slide on the shell.

The top end of the movable contact piece can move along with the push button.

The reset spring in the push button can move and compress along with the push button.

Compared with the prior art, the invention has obvious beneficial effects, and the technical scheme shows that: according to the invention, the static contact piece and the movable contact piece are respectively inserted into the base, the base is clamped into the lower end of the shell, the washer is sleeved outside the shell, the nut is screwed in, the push button is respectively placed into the reset spring, the snap spring and the steel ball to be clamped into the upper end of the shell, the top end of the movable contact piece penetrates through the shell to be inserted into the push button, and the two reset springs respectively abut against the raised head arranged at the top end of the base. When the push button is pushed leftwards and rightwards, the push button drives the movable contact piece to move, and when a contact on the movable contact piece is contacted with a contact on the static contact piece, the switch circuit is switched on, and the electric signals are converted; simultaneously; when the button is pushed, reset spring compression energy storage, two steel balls of pushing button both sides are to middle shrink motion and compression snap spring, when the steel ball slides from the recess of casing intermediate position to the recess of both sides position, the action targets in place and provides the handfeel that targets in place, release behind the drive force to pushing the button, because of reset spring's elasticity is greater than the locking force of casing recess to the steel ball, push the button under reset spring's effect, push the button and move to the intermediate position, two steel balls are to pushing button middle shrink motion and compression snap spring, when the steel ball slides from the recess of the both sides position of casing to the intermediate position, push the button and get back to the intermediate position and provide and target in place and feel, when pushing the button and reseing, drive the contact piece and get back to the neutral position, and the separation of quiet contact piece, switching circuit breaks off. The toggle switch has the advantages that the good in-place hand feeling of the three-position two-side locking toggle switch is realized, and the self-resetting function is realized.

Detailed Description

The invention is further described with reference to the following drawings and detailed description.

The invention discloses a three-position self-resetting toggle switch which is characterized in that a switch body is arranged on the switch body; the static contact piece 7 and the movable contact piece 8 are respectively inserted into the base 6, the base 6 is clamped into the lower end of the shell 2, the washer 9 is sleeved outside the shell 2, the nut 10 is screwed in, the push button 1 is respectively placed into the reset spring 3, the snap spring 4 and the steel ball 5 and clamped into the upper end of the shell 2, the top end of the movable contact piece 8 penetrates through the shell 2 and is inserted into the push button 1, and the two reset springs 3 respectively abut against the raised head 11 arranged at the top end of the base 6.
