Release time:2019-11-05    Clicks: Click

What kind of switch is the multidirectional toggle switch, what are its specific characteristics and how should it be calculated? Let's give you a detailed introduction.
Main design of multi direction toggle switch
The switch industry is an industry full of vitality in the era of electronic and information technology. The market is increasing year by year, and the high-tech information electronic equipment has developed to high reliability and multi-function. The multi-directional toggle switch has the characteristics of compact structure, long service life, multi-function, high reliability and high technology content. It is a high-tech product in today's switch industry.
1 functional and structural characteristics
The product integrates the function features of button switch and button switch. It is a multi-functional, multi-directional (left and right, up and down) and automatic reset combination switch, which has both vertical push (button) function and elbow left and right pull (button) function.
When entering the toggle state, press the state to stop the action; when entering the press state, the toggle state to stop the action.
2 Analysis and calculation of main parameters
2.1 insulation resistance analysis insulation resistance is one of the important indicators of the switch, which is the guarantee to ensure the safe use of the switch. The greater the insulation resistance is, the higher the safety of the switch is. Therefore, when selecting plastic materials (especially the base), in addition to considering the thermal deformation temperature and shrinkage, it is necessary to consider the size of the insulation resistance. According to the theoretical basis, the insulation resistance is the parallel result of volume resistance and surface resistance, that is, the insulation resistance R is = + (2.1)
Where: R - insulation resistance, m Ω; RV - Volume insulation resistance, m Ω; RS - surface insulation resistance, m Ω; RV = ρ V × D ÷ s; rs = ρ s × B ÷ s;
Where: ρ V - volume resistivity, Ω; ρ s - surface resistivity, Ω cm; D - shortest distance between conductors; B - creepage distance; s - corresponding area between conductors.
From the above formulas, it can be seen that the main factors affecting the insulation resistance are: Volume insulation resistance (volume insulation resistance coefficient), surface insulation resistance (surface insulation resistance coefficient), the shortest distance between conductors, creepage distance, and water absorption of materials.
