Description
Affiliated technical field
The utility model relates to a kind of switch, especially a kind of alarm switch.
Background technology
Existing alarm is usually by sensor-triggered work such as infrared ray or microwaves, and the shortcoming of existence mainly is that these transducers cost an arm and a leg, and the easily generation wrong report that is interfered.
Summary of the invention
Cost an arm and a leg in order to overcome transducers such as existing alarm middle infrared (Mid-IR) or microwave, the deficiency that is subject to disturb, the utility model provides a kind of alarm switch, and this alarm switch is simple in structure, stable performance.
The technical solution adopted in the utility model is, a kind of alarm switch, comprise support, sliding bolt, sensitive switch, plectrum, support is provided with sliding bolt, and the head of sliding bolt is connected on the support by connecting line, and the neck of sliding bolt is provided with spring, sliding bolt is provided with groove, one side of sliding bolt is provided with sensitive switch, and the button of sensitive switch is other to be provided with plectrum, and the outer end of plectrum is pressed in the groove of sliding bolt.
Pulley is equipped with in the outer end of described plectrum.
Because the support of alarm switch is provided with sliding bolt, the head of sliding bolt is connected on the support by connecting line, the neck of sliding bolt is provided with spring, sliding bolt is provided with groove, one side of sliding bolt is provided with sensitive switch, the other plectrum that is provided with of the button of sensitive switch, the outer end of plectrum is pressed in the groove of sliding bolt, therefore, and when the people touches or cuts off connecting line, sliding bolt is moved, thereby make the sensitive switch closure by plectrum, make circuit turn-on, thereby trigger alarm, therefore this alarm switch is simple in structure, stable performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure chart of embodiment alarm switch;
Fig. 2 is the connecting line of the embodiment alarm switch working state figure that plectrum is depressed when coming loose;
Fig. 3 is the working state figure that connecting line when tension plectrum of embodiment alarm switch is depressed;
Embodiment
As shown in Figure 1 to Figure 3, a kind of alarm switch, comprise support 1, sliding bolt 2, sensitive switch 3, plectrum 4, support 1 is provided with sliding bolt 2, and the head of sliding bolt 2 is connected on the support 1 by connecting line 5, and the neck of sliding bolt 2 is provided with spring 6, sliding bolt 2 is provided with groove 7, one side of sliding bolt 2 is provided with sensitive switch 3, and the button of sensitive switch 3 is other to be provided with plectrum 4, can press the button of sensitive switch 3 when plectrum 4 is depressed; Pulley is equipped with in the outer end of plectrum 4, and the pulley of plectrum 4 outer ends is pressed in groove 7 places of sliding bolt 2.When touching the connecting line 5 of alarm switch when burglar's invasion, sliding bolt 2 will move, thereby the groove 7 of sliding bolt 2 is left in the outer end that makes plectrum 4, plectrum 4 is depressed the shift knob of sensitive switch 3, make switch closure, make circuit turn-on, thereby can trigger alarm, this alarm switch is simple in structure, stable performance.
