Description

Dip switch structure improvement

This creation is about a dip switch, especially a dip switch structure that is easy to operate and improves the use yield and avoids elastic fatigue and durability.

Dip switch is an address switch used for operation control, which mainly uses the binary coding principle of 0/1, and there are many types of dip switches on the market at present, such as dip digital switches and key-type dip switches. The dip switch can be used in different electronic devices to be used as code setting, identification code setting, etc., and as shown in FIGS. 1 and 2, it is a conventional dip switch 1, in which the dip switch 1 It mainly includes a switch body 11 and a plurality of push buttons 12 and 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 elastics An arm 132, and the conductive elastic piece 13 is disposed at the bottom of the push button, and the conductive elastic piece is driven to reciprocate by turning the push button, so that the elastic arms 132 on both sides thereof contact or not contact the conductive terminal 14, The purpose of causing current conduction or disconnection, however, the elastic arms 132 of the conductive elastic pieces 13 are made of conductive metal materials, and are bent at a predetermined angle by stamping during the manufacturing process to make the elastic arms 132 It has a slight elastic effect, but because the metal itself has a certain elasticity coefficient, when the bending of the metal material is completed, the predetermined angle of the original bending is affected by the characteristic that the material itself will rebound again, which cannot be effectively fixed at The required bending angle, and then poor contact occurs In fact, and the internal space of the switch body 11 is limited, it will cause the length of the arm 132 formed on both sides of the conductive spring piece to be limited, and under the condition that the space and the length of the arm are limited, if you want to achieve good contact Conduction, the conductive elastic piece 13 must have a greater pressure against the conductive terminal 14, but when the pressure is greater, the conductive elastic piece 13 is more likely to deform. If the pressure that the conductive elastic piece 13 can withstand exceeds, it will be excessive. The deformation causes the conductive elastic sheet 13 to lose its elasticity and cannot rebound, or even to return to the original angle of the conductive elastic sheet 13 and other problems occur. Moreover, when the conductive elastic sheet 13 is stamped and formed, the bending angle of the conductive elastic sheet 13 may also be too large, resulting in sliding resistance The increase and the movement are not smooth, or the angle of the conductive elastic sheet 13 is too small, which causes the push button 12 to loosen when moving, and may even cause unstable contact.
