The C&K Switches KSC DCT Series Tactile Switches are now available from Littelfuse. The sealed IP67-rated, momentary-action tactile switches for surface-mount technology (SMT) in the KSC DCT (Dual Circuit Technology) series are intended to provide customers with a satisfying, customizable tactile experience.
The KSC DCT, which measures only 6.2 x 6.2 x 5.2 millimeters, is said to be the first tactile switch to have single pole double throw (SPDT) capabilities. The switches have a soft actuator with a 300K life cycle lifespan and an operating force of 4.75N (+/-1.25N).
The KSC DCT Series offers exceptional, long-term reliability in even the dustiest environments, making it a sensible option for smooth integration into current or next-generation designs.
The KSC DCT Tactile Switches offer these key features and benefits:
- SPDT Functionality: Added reliability due to one input and two outputs in a single tactile switch.
- Compact Footprint: Fits applications where space is limited.
- IP67 Sealing: Provides high contact reliability, protecting against dust and water ingress.
- J-Bend SMT Package: Enables standard assembly mounting using typical pick-and-place machines. (Gullwing-type terminations are also available.)
- Cost-Efficient: SMT makes it ideal for high-volume applications.
The KSC DCT Series Tactile Switches are ideally suited for:
- Transportation: Automotive door handles, EV charging station units, two- and three-wheelers.
- Consumer Electronics: Power tools, lawn mowers, snow blowers, home appliances.
- Medical Devices: Electrosurgical instruments, portable medical devices.
- Industrial Applications: Elevators, fire alarm equipment.
The KSC DCT Series offers exceptional, long-term reliability in even the dustiest environments, making it a sensible option for smooth integration into current or next-generation designs.
How it works: Single Pole Double Throw (SPDT) tactile switches have a feature called Dual-Circuit Technology (DCT) that generates two separate output signals inside its body. Common, Normally Close (NC), and Normally Open (NO) pins are included on the KSC DCT tactile switch.
In the event that the designer decides to employ both NC and NO circuits. In that scenario, it offers a Changeover signal that enables the designer to specify the signal’s logic using both circuitries and behave in accordance with the logic.
For instance, both NC and NO circuits are employed in an automobile door handle before a decision is made. The NO contact is open and the NC contact is closed, indicating that the logic is at rest. When a user pushes the button, nothing will happen until the NC contact is open and the NO contact is closed.
