Abstract
A novel magnetic switch comprises a shell, a switch cover on the shell, a contact block in the shell, wherein one end of the contact block is connected with conductor and another end is connected with a permanent magnet by a connection rod; steps are arranged in the shell and a return spring is sleeved on the connection rod and one end is connected with the contact block and another end is mounted in the steps. The contact block is connected with the magnet by the connection rod, the spring is sleeved on the connection rod and the contact block in-place and reset is controlled by the magnetic force and the spring. The structure is simple and the product reliability is high. The novel magnetic switch is used for the fridge door, the car door and the security door and as power supply switch or sensor.
Description
Technical field
The utility model relates to a kind of appliance switch, is specifically related to a kind of switch that adopts magnetic force control.
Background technology
The switch that is used for the control circuit break-make generally is to finish break-make work with the form of mechanical reed contact, after using after a while, owing to reasons such as the mechanical reed energising is heated, mechanical wears, the elasticity of mechanical reed reduce gradually and make poor contact of contacts, the difficult problem that resets, cause switch failure.
Summary of the invention
The purpose of this utility model is that a kind of long service life will be provided, the magnetic switch that reliability is high.
The purpose of this utility model is achieved in that a kind of novel magnetic switch, comprises shell, and shell is provided with switch cover, is provided with contact block in the shell, and contact block one end is connected with lead, and the other end is connected with permanent magnet by connecting rod; Be provided with step in the shell, return spring is sleeved on the connecting rod, and an end is connected with contact block, and the other end places on the step.
The magnetic switch that the utility model provides is connected with magnet by connecting rod by adopting contact block, is set with the structure of spring on the connecting rod, utilizes magnetic force and spring to control putting in place of contact block and reset, and is simple in structure, the reliability of products height.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model when being in closed conducting.
Fig. 2 is that the utility model is in the structural representation when disconnecting.
Embodiment
As depicted in figs. 1 and 2, a kind of novel magnetic switch comprises shell 1, and shell 1 is provided with switch cover 2, is provided with contact block 3 in the shell 1, and contact block 3 one ends are connected with lead 6, and the other end is connected with permanent magnet 5 by connecting rod 4; Be provided with step 7 in the shell 1, return spring 8 is sleeved on the connecting rod 4, and an end is connected with contact block 3, and the other end places on the step 7.
Operation principle of the present utility model is as follows: when permanent magnet 2 during away from iron class material, under the effect of return spring 8, contact block 3 is communicated with lead 6, and switch is in conduction state; When permanent magnet 5 during near iron class material, permanent magnet 5 overcomes the elastic force of return spring 8 and moves, and drives contact blocks 3 actions by connecting rod 4, contact block 3 is separated with lead 6 and cuts off circuit; Away from permanent magnet 5, then magnetic force weakens as iron class material, and the elastic force of return spring 8 will be greater than magnetic force, contact block 3 stressed resiliences, and circuit is conducting once more.The utility model can be used for refrigerator doors, automotive door, antitheft door etc. to be located, and uses as mains switch or transducer.
