Switching power supply and linear power supply, both interest rates increase as output capacity increases, but at different rates. A power supply, a switching power supply generally consists of a pulse width modulation. The cost of linear power supply is higher than that of switching power supply at a certain output power point, which is called the cost reversal point. With the development and innovation of power electronics technology, Membrane Switch power supply technology is also being innovated. This benefit reversal point is increasingly transferred to the low output power end, which provides a broad space for the development of Membrane Keypad Switch power supply.
The novel photoelectric switch is an active photoelectric detection system based on pulse modulation. The cold light sources used include infrared light, red light, green light, blue light, etc., without contact, fast, no damage. Control the state and action of various solids, liquids, transparent bodies, black bodies, soft bodies and smoke. Dip switch adopts integrated circuit technology and SMT external device technology to produce a new generation of photoelectric switching devices with intelligent functions such as delay, widening, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis.
The disadvantages of waterproof and explosion-proof switch contact type travel switch are low response speed, poor accuracy, easy to detect the damage of the measured object and short life, and the proximity of the transistor proximity switch is short, cannot directly detect non-metallic materials. The new photoelectric Button switch overcomes the above shortcomings, and has the characteristics of small size, multiple functions, long life, high precision, fast response, long detection distance, light resistance and so on.
