TTI offers surface mount switches from C&K
Long life KSC ULL tact switches from C&K are now available from TTI. The space saving KSC201, KSC401, KSC701 and KSC1001 series can complete five million cycles. They are available in J bend and gullwing terminal styles.
The surface-mount switches are sealed to IP-67 and are compact for use in elevators, joysticks, game controllers, automotive controls, medical and aircraft applications.
The 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.
The switches have a single-pole, single-throw (SPST) contact arrangement and have tactile feedback. They measure just 6.2 x 6.2mm, with four heights (3.5, 4.3, 4.9 and 5.2mm) from the PCB according to the series selected.
Travel is 0.3mm with soft actuator to absorb mounting tolerances. Shared features of all KSC Series long life SMT tact switches include dielectric strength of 250Vrms or less and contact resistance up to 0.1Ohm, insulation resistance up to 10MOhm, and bounce time up to 1ms. The KSC Series switches are rated for 32V DC maximum voltage, 50mA maximum current for silver contacts (-40 and +85 degree C), and 10mA maximum current for gold contacts (-40 and +125 degree C).
