Standard options include integrated LED lighting, decoupling diodes or bridges, and 4mm drive travel.
The MX switch series offers unipolar contacts with a rated voltage of 12VDC, durability with 50 million operations, and a range of actuation types, strokes, and pressures. The standard drive is linear with a click at the pressure point, a stroke of 3mm-0.5mm, and an initial force of 25cN min. The standard contact lead spacing is 19.05mm, which is fixed with a snap-in frame or a PCB solder pin. LED lighting is available in red, green or yellow.
The MX keyboard switch has an IP40 protection rating, an operating temperature of -40C to + 70C, and can operate at up to 95% non-condensing humidity. The insulation is made of UL 94 HB thermoplastic.
For thin applications, CHERRY ML key module 20 may provide a reliability million operations, the electrical and environmental specifications MX same, and the actuator travel is 3.0-0.5mm, only a nominal lead pitch of 18mm PCB installed
in addition to Separately available to OEM manufacturers, the switch MX key module can be used in Cherry's many standard and compact keyboard designs, including magnetic card readers and chip card readers. The company says that ML key switches can be used in standard compact keyboard designs.
