简体中文Piezo switch
Piezo switch are based on a solid-state output allowing for a very long life expectancy (more than 50 millions cycles), ideal for demanding applications where reliability is most important.The flat actuation surface is completely closed, preventing the intrusion of liquids or other contaminants, perfect for surface cleaning required in the medical and food-processing industries.
High performance sealing (IP68 and IP69K) is achieved due to the one-piece construction of the switch.
The screw-machined metal housing construction and LANGIR’s vertical integration allow for the manufacture of a variety of shapes.
Plastic Piezo switch
Plastic piezo switch uses a piezoelectric chip. The surface layer, that is, the part seen by the user, can print, cover or press out the required information. Plastic piezo wafer is inserted into a pressed insulating layer (sleeve), which is sandwiched between two conductive sheets that make up the switch contacts. It is supported by the last plate. Compared with resistive membrane switch, some advantages of plastic piezo switch are as follows: 1. Plastic piezo effect is the characteristic of some specific crystalline silicon materials, including natural quartz crystal and artificial ceramic materials. When mechanical pressure is applied to these materials, the lattice structure will produce voltage and charge directly proportional to the pressure. 2. Plastic piezo switches require almost negligible physical movement, usually between 1 μ m and 10 μ m, to generate usable switching voltage or charge. 3. It is the simple exertion of external force rather than physical movement that produces the output of switch element.
19mm Piezo switch
These piezo switch (PZ series) available with different bushing diameters(12~30mm), material and shapes. Sealed to IP68 or IP69K, easy to clean metal surface, long life (50 million cycles), ring or dot illumination, custom configurations. With their robust stainless steel, brass or anodised aluminium housings, these innovatively designed switches are protected to IK10 impact resistance and IP67 sealing requirements, which makes them ideal for use in exposed public buildings and areas.
30mm Piezo switch
These piezo switch (PZ series) available with different bushing diameters(12~30mm), material and shapes. Sealed to IP68 or IP69K, easy to clean metal surface, long life (50 million cycles), ring or dot illumination, custom configurations. 30mm piezo switches are ideal to use and task piezoelectric glass plates. The combination of these two devices provides a waterproof solution for underwater diving lights or other products used in harsh environments. It can be directly connected to a piezoelectric glass plate to create a latching high-current switch for battery-powered devices. The piezoelectric switch is a momentary action device, even if it is pressed for a long time, it can only generate a maximum pulse of about 200-400 milliseconds.
