Structure and Application of Light Touch Switch in Circuit

Release Time:2019-01-07

Touch the switch for some circuits and lines when it is good to use, so we give you to understand the problems on the touch switch keys, to ensure normal use, the following is a detailed introduction for you to browse.
Touch switch is a kind of button with its own circuit. Usually, the top layer is a panel with text or pattern composed of PET or PC, the bottom layer is a conductive circuit, the middle layer is a double-sided adhesive made of PET material, which simulates the form of switch and acts as isolation. The bottom layer is usually the contact and connection line on PET material. The light touch key switch is a switch that uses the button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The light touch button switch is a kind of master electric appliance with simple structure and wide application. In the electric automatic control circuit, it is used to manually send out control signals to control contactors, relays, electromagnetic starters, etc. When the finger is pressed on the key position of the surface layer, the key contact points of the surface layer contact with the corresponding parts of the lower layer to form a current connection.
Light touch switch manufacturer's commodities use integrated circuit technology and SMT surface equipment technology to produce a new generation of optoelectronic switchgear, which has the intelligent functions of delay, broadening, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. This novel photoelectric switch is an electronic switch of an automatic photoelectric detection system with pulse modulation. The cold light sources used include infrared light, red light, green light and blue light, etc. It can be non-touch, and can quickly and nondestructively control the conditions and actions of various solid, liquid, transparent, black body, soft body and smoke materials. Touch stroke switch driven by waterproof and explosion-proof switch has some shortcomings, such as low response speed, poor accuracy, easy damage to detected objects and short life, while transistor can not directly detect non-metallic materials because of the short action interval between transistor and switch. However, the new photoelectric switch overcomes the above shortcomings, and has small size, multi-function, long life, high precision, fast response speed, long detection interval and strong anti-light, electric and magnetic disturbance ability. Introduction to the types of commodities and the mechanical function standards of the toggle switch manufacturer The toggle switch is to turn the circuit on or off by toggling the switch handle, and then reach the intention of the toggle circuit. The common types of switch are unipolar bipolar, unipolar three, bipolar bipolar and bipolar three. It is usually used in low-voltage circuit, and has the characteristics of sensitive slider action and stable function.
In this way, we can understand and relax the use of touch switch more easily. If you want to buy touch switch, you can contact us.
