Abstract
The utility model relates to a panel mount sparkless safety power supply switch. The purpose is the characteristics that the switch that provides should have power load sparkless, safe and reliable when carrying out closure or opening operation. Technical scheme is: panel mount sparkless safety power supply switch is including switch seat, the connection panel and swingingly location at least one button on the panel that can reciprocate on the switch seat, still install hall sensor and contactless semiconductor switch component on this switch of its characterized in that, the magnet that triggers hall sensor and use is equipped with on the button, the return circuit that contactless semiconductor switch component inserted power and load is and control end switch -on hall sensor. The magnet dress is served in the swing of button to make magnet follow the signal trigger motion of the swing transform of button for hall sensor. Contactless semiconductor switch component is the silicon controlled rectifier.
Description
Technical field
This utility model relates to a kind of on and off switch, especially panel type no-spark safety power switch, it is adaptable to industry inflammable, explosive and the occasions such as colliery, combustion gas, fuel oil, high dust enterprise.
Background technology
The operation principle of traditional panel type on and off switch, it is to carry out closing or opening operation by power source loads, but contact can occur electric spark when operation, this is the most unallowed in industry inflammable, explosive and occasion, because this will trigger the flammable explosive gas in environment or dust, thus causes significant explosion and pyrophoricity accident.
Utility model content
The purpose of this utility model is to provide the improvement of a kind of panel type on and off switch, and this switch should have power source loads to carry out closing or no-spark, safe and reliable feature during opening operation.
For realizing object above, this utility model have employed following technical scheme:
Panel type no-spark safety power switch, the panel including switch base, being connected on switch base and at least one button being the most swingingly positioned on panel；It is characterized in that on this on and off switch, being also equipped with Hall element and contactless thyristor, equipped with the Magnet of triggering Hall element on described button, described contactless thyristor accesses the loop of power supply and load and controls to terminate logical Hall element.
Described magnet cartridge, on the swinging end of button, is transformed to the signal of Hall element triggers motion so that Magnet follows the swing of button.
Described contactless thyristor is controllable silicon.
The beneficial effects of the utility model are, owing to during current switching, no-spark produces, it is thus possible to be to reliably applied to inflammable, explosive environments (such as in the occasion that may have gas leak), it is ensured that the safety of life and property of the people；Additionally, due to remain the profile of original " panel type on and off switch " and operating habit and feel, this utility model can directly be replaced installation or change in the installation site of original " panel type on and off switch " and use, thus very convenient.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model.
Fig. 2 is electrical structure schematic diagram of the present utility model.
Detailed description of the invention
Panel type no-spark safety power switch shown in the drawings, the panel 1 including switch base 2, being connected on switch base and the button 4 (number of keys sets as required, such as single-button switch, double key switch, three key switches, four key switches or the key switch of band socket) being the most swingingly positioned on panel by button axle 4-1；Above with existing panel type on and off switch similar (clear for drawing, figure omits the original papers such as binding post).
Improvement of the present utility model, it is that Hall element 6 and contactless thyristor 3 are installed on this switch base, equipped with the Magnet 5 triggering Hall element on described button, described contactless thyristor accesses the loop of power supply (220V alternating current power supply) and load, and controls to terminate logical Hall element.The described preferred controllable silicon of contactless thyristor.
In figure visible: described magnet cartridge is on the swinging end of button, and Hall element is then arranged close to the corresponding position of button；So, the machinery produced during key presses swings (back and forth movement) just can make Magnet produce certain change with the distance of Hall element, makes Hall element carry out signal triggering.Obviously, described Hall element also can replace with tongue tube.
In order to keep original " panel type on and off switch " original operating habit and feel, this utility model is consistent with reservation in the common overall dimensions of panel type on and off switch, outward appearance and operating habit and feel, so can conveniently replace common panel type on and off switch, to facilitate replacement to install.
The equal buyable of all electronic devices and components in this utility model obtains.
The foregoing is only preferred embodiment of the present utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
Claims (3)
1. panel type no-spark safety power switch, the panel (1) including switch base (2), being connected on switch base and at least one button (4) being the most swingingly positioned on panel；It is characterized in that on this on and off switch, being also equipped with Hall element (6) and contactless thyristor (3), equipped with the Magnet (5) of triggering Hall element on described button, described contactless thyristor accesses the loop of power supply and load and controls to terminate logical Hall element.
Panel type no-spark safety power switch the most according to claim 1, it is characterised in that: described magnet cartridge is on the swinging end of button.
