Designed to withstand very intensive use of up to five million cycles, KSC ULL switches are suitable for elevators, joysticks, game controllers, automotive controls, medical and aircraft applications.
These ultra-long life switches can be customised by varying the hardness of the silicon actuator to change the switch actuation force and pre- and post-travel parameters can also be adjusted for different requirements according to application.
KSC ULL switches have a single-pole, single-throw (SPST) contact arrangement and deliver excellent tactile feedback.
They are compact, measuring only 6.2mm x 6.2mm, with four heights (3.5mm, 4.3mm, 4.9mm and 5.2mm) from the PCB according to the series selected.
A choice of either G or J terminations saves further PCB real estate. Travel is 0.3mm with soft actuator to absorb mounting tolerances.
Shared features of all KSC Series ultra long life SMT tact switches include: dielectric strength ≥250Vrms, contact resistance <0.1Ω, insulation resistance >10MΩ, and bounce time <1ms. KSC Series switches are rated for 32VDC maximum voltage, 50mA maximum current for silver contacts (-40°C and 85°C), and 10mA maximum current for gold contacts (-40°C and 125°C).
The switches are packaged on continuous tape and reel in quantities spanning 1,000 to 2,000 pieces.
