Fig. 1 is the structural representation of a kind of touch switch of the prior art;
The structural representation of a kind of Elastic Contact formula switch that Fig. 2 provides for the utility model embodiment 1.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
The structural representation of a kind of Elastic Contact formula switch that Fig. 2 provides for present embodiment.Referring to diagram, the touch switch that present embodiment provides mainly comprises: housing 200, rotary switc axle 201, contact chip (2021,2022,2023,2024) and compression spring 301, wherein rotary switc axle 201, contact chip (2021,2022,2023,2024) and compression spring 301 all are arranged in the housing 200.Wherein the annexation of each several part and position are mainly as follows:
Rotary switc axle 201 is fixed on the middle part of housing 200 inner chambers, this rotary switc axle 201 can be rotated activity under user's turn operation, have a plurality of (can but be not limited to two, three, four etc.) to electrically contact piece (2011,2012,2013,2014) in that the periphery of rotary switc axle 201 is exposed, this exposed number that electrically contacts piece (2011,2012,2013,2014) be identical with the number of contact chip (2021,2022,2023,2024).Each contact chip (2021,2022,2023,2024) is separately fixed at the inwall of housing 200, when the end of predetermined certain or a plurality of contact chip (such as 2021,2022,2023) respectively with rotary switc axle 201 on electrically contact piece (such as 2011,2012,2013) when contacting respectively, this contact switch is in conducting state.Such as:
Referring to shown in Figure 2, in the present embodiment, can set four contact chips (2021,2022,2023,2024), four that setting is exposed on rotary switc axle 201 electrically contact piece (2011,2012,2013,2014), when first contact chip 2021, second contact chip 2022, the 3rd contact chip 2023 respectively with rotary switc axle 201 on first electrically contact piece 2011, second electrically contact piece 2012, when the 3rd contact block 2013 contacts, this moment switch be in conducting state; Otherwise switch is in off-state.
In addition, all be connected with a compression spring 301 at the end of each contact chip (2021,2022,2023,2024), the other end of each compression spring 301 is fixed on the inwall in the housing 200.
Therefore, because in the present embodiment, end at each contact chip (2021,2022,2023,2024) is provided with a compression spring 301,301 pairs of each contact chips of each compression spring (2021,2022,2023,2024) play a part to hold in the process of using, can play relatively-stationary effect to this contact chip (2021,2022,2023,2024), the problem that can avoid contact chip (2021,2022,2023,2024) in use to deform, be shifted.
And, because compression spring 301 also has certain elastic force, the user is when this rotary switc axle 201 of turn, the elasticity of this compression spring 301 can allow this rotary switc axle 201 turns again, when this rotary switc axle 201 exposed electrically contact piece and contact chip over against the time, the elastic force of this compression spring 301 can also play the active force of propelling to the end of the contact chip that is attached thereto, help guaranteeing the contact that electrically contacts piece that contact chip and rotary switc axle 201 are exposed, help improving the electrical contact performance of switch.
In addition, in the implementation process of carrying out this switch, the inventor finds through experiment repeatedly: preferably compression spring 301 is vertically set on housing 200 inwalls, thereby make 301 pairs of contact chips that are attached thereto (2021 of compression spring, 2022,2023,2024) has elastic force perpendicular to inwall, so not only help contact chip (2021,2022,2023,2024) location also further helps guaranteeing contact chip (2021,2022,2023,2024) with on the rotary switc axle 201 exposed electrically contact piece (2011,2012,2013,2014) contact steadiness.
In the present embodiment, can but do not limit and housing 200 is arranged to square, but also be not limited to it is arranged to cuboid or other shape (circle etc.).
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
