Conductive rubber is used as the switch of the contact path, and the conductive rubber is used as a conductive rubber switch. Switch feel good, but the contact resistance is large, generally in the 100 one 300n. The structure of key switch is on the button down, make contact spring or conductive rubber block contact welding, forming path.<br />The operating force and the reed key switch the state of the. Began to force and the spring compression distance is more than the reed compressed to 5% - 70% operating force suddenly reduces, and accompanied by a &quot;tick&quot; sound. Guide turtle rubber switch generally has two kinds of structure. The operating force curve varies with the geometry of the rubber block.<div class="para" label-module="para" style="font-size: 14px; word-wrap: break-word; color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 24px; zoom: 1; font-family: arial, 宋体, sans-serif;"></div>]]></description><pubDate>Fri, 05 Aug 2016 10:45:49 GMT</pubDate><author>jason</author></item><item><title>What is a key switch?</title><link>http://en.dgycdz.com/company_news_show_185.html</link><description><![CDATA[<div class="para" label-module="para" style="font-size: 14px; word-wrap: break-word; color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 28px; line-height: 24px; zoom: 1; font-family: arial, 宋体, sans-serif;"></div>The key switch is mainly refers to the touch button switch, called touch switch.

The correct name should be called for vibration sensor is in the induction of vibration force the size of the induction result is passed to the circuit device, and makes the circuit to start working on the electronic switch. It was also known as the vibration switch, there are some known as a slide switch or shaking switch, in fact, these names is not entirely correct. The term generally separated into two categories, the spring switch and ball switch. In fact, strictly speaking, the vibration switch should simply refer to the spring switch, does not include the ball switch. The vibration switch the name seems to be just as &quot;vibration&quot; and &quot;shock&quot; is a homonym, caused by a typo, due to a long time is recognized by the people of a fault. Strictly speaking, the vibration switch is called the error. And other names, such as sliding switches, shaking switches, etc., should refer to the ball switch. For convenience, the industry generally also unified the spring switch with the ball switch two is called the vibration switch. Vibration switch is mainly used in electronic toys, small household appliances, sports equipment, as well as various types of anti-theft devices and other products. Because of its flexible and sensitive trigger, the vibration switch has become an indispensable electronic component in many electronic products.]]></description><pubDate>Fri, 05 Aug 2016 10:38:56 GMT</pubDate><author>jason</author></item><item><title>Switch features?</title><link>http://en.dgycdz.com/company_news_show_181.html</link><description><![CDATA[<div class="para" label-module="para" style="font-size: 14px; word-wrap: break-word; margin-bottom: 15px; text-indent: 2em; line-height: 24px; zoom: 1; font-family: arial, 宋体, sans-serif;"></div>Toggle switch with integrated circuit technology and SMT surface mount technology and manufacturing of a new generation of photoelectric switches, with delay and broadening, synchronization, anti interference, high reliability, stable working area and self diagnose function. This novel photoelectric switch is a kind of the pulse modulation of the active optical detection system electronic switch, by the use of cold light source with infrared and red light, green light and blue light can be non-contact, no damage to rapidly and various solid, liquid, transparent body, bold, soft body and smoke control and material state and action.<br />Drive water proof switch contact type travel switch response speed is low, poor accuracy, contact detection easily damaged by the test material and the short life of the shortcomings, and transistor proximity switch is a short distance, cannot directly detect non-metallic materials. But the new photoelectric switch overcomes the defects, and has the advantages of small size, multiple functions, long service life, high precision, fast response, high detection distance, light resistance, electric and magnetic interference ability.<br />Toggle switch of variety and mechanical performance specifications of the toggle switch is through the toggle switch handle to make the circuit be switched on or off, so as to achieve the purpose of switching circuit.
