Advanced tactile switches provide SMT and IP67 for high-efficiency applications

Littelfuse, Inc., has announced the C&K Switches EL2 Series Tactile Switches. These standard-size, sealed SMT tactile switches are created for general-purpose switching applications and offer enhanced performance, higher component density, and improved reliability for various electronic devices.

The switches stand out due to their market-standard size designs, IP67 sealing, and versatility in various applications. With heights of 3.5mm and 5.2mm and actuation forces of 2 newtons for a light touch and 3.5 newtons for more firm pressure to activate the switch, the series ensures seamless integration into existing designs while providing exceptional contact reliability in dusty environments.

The switches ensure ease of integration into various applications and provide IP67 sealing with high contact reliability, protecting against dust and water ingress. Their J-Bend SMT package enables standard assembly mounting using typical pick-and-place machines. The switches are ideal for high-volume applications.

"Littelfuse engineers are committed to solving the problems relevant to the layout size of our customers' unique applications, as well as the limitations of specific environments and electrical loads," said Gavin Xu, technical development manager, Electronics Business Unit Engineering. "The EL2 demonstrates the high level of design philosophy of the engineers and the careful planning of the product management team. The EL2's resulting stability and reliability will perfectly match applications in medical, high-precision instruments, consumer electronics, and other industries."

With a lifecycle of 200,000 cycles and an IP67 rating, the EL2 Series ensures long-term reliability and performance in various applications. The addition of the EL2 Series to the C&K tactile switch portfolio meets the need for basic tactile switch requirements and IP67 sealing at a competitive price. The compact EL2 Series tactile switch allows designers to incorporate the switch into standard and harsh applications.

The switches deliver superior performance reliability for consumer electronics, building automation, medical and industrial applications.
