Abstract
The utility model relates to a pull switch, comprising a rubber wheel with saw teeth, and the state of the switch can be conveniently identified through the pull switch. The saw teeth of the rubber wheel are six, and the elastic static contact sheet of the pull switch is pressed on the rubber wheel. The pull switch is characterized in that: as the height of one group of the three separated saw teeth is larger and one group is smaller, the falling head of the elastic static contact sheet is different, accordingly, different sounds are generated, and the state of the pull switch can be identified. The state of the switch can be conveniently identified through the pull switch by listening to the sound; the pull switch has simple structure, and the cost cannot be increased.
Description
(1), technical field
The utility model relates to a kind of pulling switch, and it can tell the residing state of switch easily.
(2), background technology
The pulling switch that uses is not being seen lamp or is not being opened under the situation of switch cover at present, is difficult to judge the residing state of pulling switch, and promptly switch is off-state or closure state.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of pulling switch, and it can tell the residing state of switch easily.Simple in structure, do not increase cost.
The technical scheme in the invention for solving the technical problem is: a kind of pulling switch, it comprises the rubber tire of band saw tooth, the sawtooth of described rubber tire has six, the elasticity static contact of pulling switch is pressed on the described rubber tire, between it is characterized in that across one group of three sawtooth tooth depth bigger, one group is less, makes the drop difference of elasticity static contact, thereby the sound that produces varies in size, to judge the residing state of pulling switch.
Since just change the sawtooth tooth depth of rubber tire, thus simple in structure, do not increase cost.Just know the residing state of pulling switch by the sound of differentiating elasticity static contact strike rubber tire.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the A-A cutaway view among the utility model Fig. 1.
(5), embodiment
A kind of pulling switch, it comprises the rubber tire 1 of band saw tooth, as shown in Figure 1.The sawtooth of described rubber tire 1 has six, the elasticity static contact 5 of pulling switch is pressed on the described rubber tire 1, it is characterized in that 4 of three elasticity movable contact springs connecting together on the rubber tire 1 near between across three sawtooth 2 tooth depths less, other three sawtooth 3 tooth depths are bigger, the drop difference of elasticity static contact 5 like this, thus the sound that produces varies in size.Pulling backguy 6, sound hour illustrates that switch is in closure state; When loud, illustrate that switch is in off-state.
The tooth depth of described two groups of sawtooth 2,3 also can be designed to above-mentioned opposite, thereby realizes: pulling backguy 6, and a sound hour switch is in off-state, and switch is in closure state when loud.
Claims (3)
1, a kind of pulling switch, it comprises the rubber tire (1) of band saw tooth, the sawtooth of described rubber tire (1) has six, the elasticity static contact (5) of pulling switch is pressed on the described rubber tire (1), it is characterized in that: across one group of the tooth depth of three sawtooth (2 or 3) bigger, one group less, makes the drop difference of elasticity static contact (5).
2, pulling switch according to claim 1 is characterized in that: three the elasticity movable contact springs (4) that connect together on the described rubber tire (1) near between across the tooth depth of three sawtooth (2) less, the tooth depth of other three sawtooth (3) is bigger.
3, pulling switch according to claim 1 is characterized in that: three the elasticity movable contact springs (4) that connect together on the described rubber tire (1) near between across the tooth depth of three sawtooth (2) bigger, the tooth depth of other three sawtooth (3) is less.
