The latest market statistics show that, China's small household electrical appliance industry in 2011still developing rapidly, small appliances than white home appliance and black home appliance of faster growth, annual growth rate of more than 10%. The Chinese small household electrical appliances sales160500000000 yuan in 2010; in 2011 the first 8months amounted to 115700000000 yuan, a conservative estimate of the year 2011will exceed 170000000000 yuan. And as with the small household electrical appliances product diversification development, on its supporting products demand also grow with each passing day, especially on the potentiometer with switch demand is extremely prominent. But China's potential market has certain limitation, relatively speaking, restrict the development of machine manufacturers, such as potentiometers manufacturers put forward higher requirements, for the whole plant development personality customization facilities, become a potential for the industry development trend. At the same time, for the production of a potentiometer with a switch manufacturers, its development, manufacturing capacity will be considered the first index of machine manufacturers, set the development of design, parts manufacturing, assembly of one-stop manufacturer will be machine manufacturers preferred supplier.
Potentiometer with switch basic situation
The potentiometer is an adjustable electronic components, which is composed of a resistor and a rotating or sliding system, by manually regulating rotating shaft or handle change the moving contact in the resistor body position is changed, the moving contact and a fixed end between the resistance value, thus changing the circuit voltage or current size.
Potentiometer with switch potentiometer is as branches, mainly in the original potentiometer is increased on the basis of a switch, with independent on-off control function. It is convenient for users to design the circuit and the appearance of products. More convenient, practical function. Eliminates the need for additional space switch and cost, household appliances control circuit is preferred.
Because of the characteristics of a potentiometer with a switch, which can regulate the current, output voltage and power control. So the market is widely used. Commonly used products : lighting dimmer, fan speed, heating temperature, electric oven, humidifier, electric water heater, electric sprayer etc. ... ... General requirements regulating the current voltage and power control can be applied.
Here are several potentiometer with a switch in the market on the basic application:
138S series: this model is mainly characterized by high power, reliable structure, through dozens of years of market tests, the main application of motor speed, large power light, temperature and other products. Such as: fan, electric oven, electric water heater.
137S series: the models in the following the save138S product basis, more compact structure, small in size slightly users design and development ( mainly used in the heater, wall switch, electric sprayer etc. ).
128S series: the model in 138S,137S products on the basis of further optimizing the structure, to a smaller, switch power can still meet their requirements, to provide users product design provides enough space. ( the main application of wall switch, small appliances etc. )
161S series: this series features small size, mainly used in lamps, audio control, low power.
168S series: This product has won the national invention and patent of appearance, it is mainly for 161S product using a short hidden, and market characteristics of application developed alternative products, its characteristic is switching from161S products mechanical instability into the electronic switch and capable of sounding. The use of a significant effect with switch long life ( not physical mechanical ) structure is simple and reliable since the introduction of deep well users. Because of its reliable simple stability of the complex physical switch uncertainty and the manufacturing cost, is really a high quality and inexpensive replacement of revolutionary products are mainly used in small power lamp and micro current power regulation and control.
Series 169: appearance has been the national patent. Product structure with168 series, specifically for outdoor camping, emergency LED lantern special specifications and customized, smaller.
