Abstract
A liquid switch relates to the improvement of switch structure. The utility model provides a liquid switch, which can replace the copper stripe switch. The liquid switch, comprising a non-conductive bottle body, has the structural key points that the inside of the bottle body is filled with mercury and both ends of the bottle body are provided with a conductor contacted with the mercury.
Description
Technical field:
The utility model relates to the improvement of construction of switch.
Background technology:
Existing switch is made with copper sheet, utilizes the copper sheet conduction; The time that this switch is used has been grown, and will produce friction between the copper sheet, so, is to produce electric spark at make-and-break contact easily just; Being used in factory etc. contains the place of explosion hazard gases and just blasts easily.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of liquid switch that replaces the copper sheet switch is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises non-conductive bottle, fills mercury in its structural feature bottle, the two ends of bottle have can with the contacted electric conductor of mercury.
The beneficial effects of the utility model:
Because fill mercury in the utility model bottle, the two ends of bottle have can with the contacted electric conductor of mercury; When bottle was vertical, promptly the utility model switch was off-state; When bottle was level, bottle two ends conductor linked together with the mercury conductor, and promptly the utility model switch is opening; Therefore the utility model is safe, can replace common copper sheet switch fully.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
Embodiment:
The utility model comprises non-conductive bottle 2, fills mercury 1 in the bottle 2, the two ends of bottle 2 have can with mercury 1 contacted electric conductor 3.
During use, liquid-level switch S of the present utility model equally is arranged in the circuit with regular tap, for example, as Fig. 2, shown in Figure 3, liquid-level switch S, lamp L, battery E are connected in the circuit, liquid-level switch S is provided with and can makes liquid-level switch S go to the knob K of 90 ° and 0 °, reaches the purpose of connection, open circuit.
Claims (1)
1, liquid-level switch comprises non-conductive bottle (2), it is characterized in that filling in the bottle (2) mercury (1), the two ends of bottle (2) have can with the contacted electric conductor of mercury (1) (3).
