Description

DIP switch structure improvement

technical field

The utility model relates to a dial switch, in particular to an improved structure of the dial switch which is convenient to operate, improves the use yield, avoids elastic fatigue and improves durability.

Background technique

The DIP switch is an address switch used for operation control. It mainly adopts the binary coding principle of 0/1. At present, there are many types of DIP switches on the market, such as DIP digital switches and push-button DIP switches. The DIP switch can be used in different electronic devices to be used for code setting, identification code setting, etc. As shown in FIG. 1 and FIG. 2, it is an existing DIP switch 1, wherein the DIP switch 1 It mainly includes a switch body 11 , a plurality of push buttons 12 , a plurality of conductive elastic pieces 13 and a plurality of conductive terminals 14 , wherein the conductive elastic pieces 13 are formed by a stamping process, and each conductive elastic piece 13 mainly has a base 131 and two elastic arms 132, and the conductive elastic sheet 13 is arranged at the bottom of the push button, and the conductive elastic sheet is moved back and forth by turning the push button, so that the elastic arms 132 on both sides contact or do not contact the conductive terminal 14, causing current conduction. However, the elastic arm 132 of the conductive elastic sheet 13 is made of a conductive metal material, and is bent to a predetermined angle by punching during the manufacturing process, so that the elastic arm 132 has a slight However, because the metal itself has a certain number of elasticity, when the metal material is bent, the original bending angle is affected by the material itself will rebound again, which makes it unable to be effectively fixed in the required position. In addition, the internal space of the switch body 11 is limited, so the elastic arms 132 formed on both sides of the conductive elastic sheet are limited in the length of the arm, and the space and the length of the arm are limited. In order to achieve good contact conduction, the conductive elastic sheet 13 must have a greater pressure against the conductive terminal 14, but when the pressure is greater, the conductive elastic sheet 13 is more likely to be deformed. The pressure that can be endured will cause the conductive shrapnel 13 to lose elasticity due to excessive deformation and cannot rebound, or even cannot return to the original angle of the conductive shrapnel 13. If the bending angle of the conductive elastic sheet 13 is too large, the pushing resistance is increased and the movement is not smooth, or the conductive elastic sheet 13 is too small, which may cause the push button 12 to be loose when moving, and may even cause unstable contact.

Therefore, there is a need for a new technical solution in the prior art to solve the above problems.
