Abstract

A magnetic control safe use switch which can be used safely. The button switch and the magnetic movable arm are sealed by a sealed shell, and the magnetic button on the outer surface of the sealed shell can move along a sliding groove. The magnetic rotating arm is fixed with a magnet end which can rotate around the other end, when the magnetic button moves to one end of the magnetic rotating arm along the sliding groove, the magnet of the magnetic rotating arm rotates along the other end under the magnetic force action of the magnetic button to open and close the button of the button switch. Therefore, the circuit is opened and closed in the closed shell, so that electric shock danger or fire accidents caused by ignition of combustible gas by electric sparks generated by switch contact can be avoided, and the purpose of safe use is achieved. The circuit control switch is mainly applied to combustible gas environments such as oil depots and gas stations, mining mine circuit switches, and switches used in humid environments such as bathroom light switches and washing machine circuit control switches.

Description

Magnetic Safety Use Switch

Technical field

The utility model relates to a circuit control switch which can be used safely when controlling a circuit, in particular to a magnetically controlled safe use switch which can be used safely in the environment of humidity, corrosion and combustible gas.

Background technique

At present, the known circuit control switch has poor safety sealing measures and can only be used safely in conventional environments. However, if it is in a humid, corrosive, or flammable gas environment, it may cause an electric shock hazard or a fire accident may occur due to the spark generated by the switch contact igniting the flammable gas.

Contents of the invention

In order to overcome the shortcomings of the existing circuit control switch, which is easy to cause electric shock hazards and fire accidents due to the ignition of combustible gases by electric sparks generated by the contact of the switch, the utility model provides a magnetically controlled safe use switch. Not only will the switch not cause electric shock hazards, but also there will be no fire accidents due to the ignition of combustible gases by electric sparks generated by the switch contact.

The technical scheme adopted by the utility model to solve the technical problem is: the closed shell seals the push button switch, the push button switch and the movable arm with magnetism, the terminal of the push button switch is located outside the closed shell and connected with the electric wire of the control circuit, and outside the closed shell Magnetic buttons on the face move along sliding slots. The magnetic rotating arm is fixed with a magnet end and can rotate around the other end, and the button of the push button switch can be opened and closed by rotating at a certain angle. When the magnetic button moves to the end with the magnet of the magnetic rotating arm along the sliding groove, the magnet of the magnetic rotating arm rotates along the other end under the magnetic force of the magnetic button to open and close the button of the push button switch. In this way, the opening and closing of the circuit occurs inside the closed casing, so there will be no danger of electric shock or fire accidents due to the ignition of combustible gas by the electric spark generated by the contact of the switch, so as to achieve the purpose of safe use.

The beneficial effect of the utility model is that it can not only be applied in ordinary environments, but also can be used in humid, corrosive, and complex environments with flammable gases, without the risk of electric shock or the ignition of flammable gases by electric sparks caused by switch contact. , to achieve the purpose of safe use.

Detailed ways

In Fig. 1, the closed casing (4) closes the button switch (9) and the magnetic rotating arm (6). The band magnetic ammonium button (1) can move along the sliding groove (3), and the connecting posts (10), (11) are connected to the electric wires of the control circuit respectively and just can work. When the magnetic button (1) is in the 0N position, the magnetic rotating arm (6) has no effect on the button (8) of the button; when the magnetic button (1) is in the OFF position, the magnet on the magnetic rotating arm (6) (7) Under the magnetic force of the magnet (1) with the magnetic button (1), turn down the rotating pair (5) and press the button (8) of the button. If the button switch (9) uses a moving button Switch, at this moment the circuit can be opened, if what the button switch (9) used is a dynamic break button switch, the circuit can be closed at this moment. Therefore, in such a switch, the opening and closing part of the circuit is completely located inside the closed casing, and if there is an electric spark in contact with it, it is also sealed inside the closed casing, and the gas will not be ignited by the electric spark to cause a fire in an environment where flammable gas exists. There is no risk of electric shock when used in a humid environment, and it is used for waterproof and safe use. Use in corrosive environments increases switch life.

Among Fig. 2, leaf spring type rotating arm (12) is made by leaf spring, and fixed iron (4) other end is fixed on the closed shell (4) on one end, and its rotation reaches by spring leaf deformation bending.

Among Fig. 3, it is a kind of moving and closing button switch that can be purchased on the market, and the button (8) of the button switch can be pressed to open the circuit, and the circuit of Fig. 4 is controlled by the magnetic control safety use switch assembled by this type of button switch.
