Rotary switch

Abstract

The invention discloses a rotary switch in a double-shaft (optional) bidirectionally-rotatable design, up to 32 switching segments. In addition, an abutting member provided with a spring cavity is provided and used to hold and confine a compression spring therein, thus when stressed and compressed, the compression spring is avoided being bent, and the abutting member can be completely embedded in a cavity of a turnplate; smooth function switching is ensured for electric products.

Description

technical field [0001] The invention relates to the related field of switch components, in particular to a rotary switch. Background technique [0002] Rotary switches are often used in electrical products, especially in electrical products that require segment switching, such as electric fans, lamps, washing machines, etc. Therefore, the rotary switch usually includes the switching of multiple functional segments, so the user can achieve the purpose of switching and switching between the functional segments as long as the adjustment knob of the rotary switch is driven. [0003] see figure 1 and figure 2 , figure 1 and figure 2 An exploded view and a perspective view of a rotary switch in the prior art provided by an embodiment of the present invention are respectively shown. Such as figure 1 and figure 2 As shown, the prior art rotary switch 1' has a multi-stage switching function, and includes: a cover body 10A', a base 10B', a rotating unit 2', a base plate 3', ...

AI Technical Summary

Problems solved by technology

Since the rotary switch 1' adopts a single-axis and one-way rotation design, the number of switching segments can reach up to 16 segments; however, for specific electrical products, the number of switching segments of 16 segments is still not enough

[0008] 2. The conductive bumps 230' of the conductive sheet 23' cannot be precisely electrically contacted with the corresponding two electrical connection areas 30'

When switching the number of stages of the rotary switch 1', turn the rotary body 20' at an angle (for example, 20°) so that the top of the turntable abutting member 4' moves out of the groove 220' and then fits into another groove 220' However, since the turntable abutment 4' is embedded in the groove 220' based on the force of the two springs 5', once the two springs 5' provide uneven forces, the turntable abutment 4' cannot be completely Move out from the groove 220' and then insert into another groove 220'; at this time, the conductive bumps 230' of the conductive sheet 23' cannot be electrically contacted with the corresponding two electrical connection areas 30' precisely, and thus It will affect the smooth function switching of electrical products
