Description

Improved structure of finger-activated switch

Background

The dip switch is an address switch for operation control, which mainly uses 0/1 binary coding principle, and there are many types of dip switches in the market, such as dip digital switch, push-button type dip switch, which can be applied in different electronic devices for code setting use, identification code setting use, etc. as shown in fig. 1 and fig. 2, the dip switch 1 is the existing dip switch 1, wherein the dip switch 1 mainly comprises a switch body 11, a plurality of push buttons 12, a plurality of conductive elastic sheets 13 and a plurality of conductive terminals 14, wherein the conductive elastic sheets 13 are formed by punching process, and each conductive elastic sheet 13 mainly comprises a base 131 and two elastic arms 132, and the conductive elastic sheets 13 are arranged at the bottom of the push buttons, the push buttons are pushed to drive the conductive elastic sheets to reciprocate, so that the elastic arms 132 at both sides of the conductive sheets are in the condition of contacting or not contacting the conductive terminals 14, however, the elastic arm 132 of the conductive elastic piece 13 is made of a conductive metal material, and is bent to a predetermined angle by stamping during the manufacturing process, so that the elastic arm 132 has a slight elastic effect, but the metal itself has a certain elastic number, so that after the metal material is bent, the original bent predetermined angle cannot be effectively fixed at the required bent angle due to the characteristic that the material itself rebounds again, and thus poor contact occurs, and furthermore, the internal space of the switch body 11 is limited, so that the length of the arm of the elastic arm 132 formed at both sides of the conductive elastic piece is limited, and under the condition that the space and the length of the arm are limited, if good contact conduction is achieved, the conductive elastic piece 13 must have a larger pressure against the conductive terminal 14, however, when the pressure is higher, the conductive elastic sheet 13 is more likely to deform, and if the pressure exceeds the pressure that the conductive elastic sheet 13 can bear, the conductive elastic sheet 13 loses elasticity due to excessive deformation and cannot rebound, or even cannot return to the original angle of the conductive elastic sheet 13, and the like, and furthermore, when the conductive elastic sheet 13 is formed by stamping, the conductive elastic sheet 13 may be bent at an excessively large angle, so that the pushing resistance is increased and the movement is not smooth, or the conductive elastic sheet 13 is at an excessively small angle, so that the push button 12 is loosened during pushing, or even the contact is unstable.

Therefore, there is a need in the art for a new solution to the above-mentioned problems.
