Littelfuse has introduced the KSC PF Series sealed tactile switches, designed to address the environmental demands of rugged electronics, including those in electric vehicle (EV) systems.
These IP67-rated momentary-action switches feature a compact 6.2 x 6.2 x 5.2 mm footprint and are optimized for potting, a process increasingly used to protect printed circuit boards (PCBs) in harsh conditions.
With growing demand for reliable components in high-vibration, high-moisture environments, such as within EV battery enclosures, control systems, and outdoor charging infrastructure, designers are seeking components that can withstand exposure to dust, fluid ingress, and thermal cycling.
The KSC PF Series supports this need with an extended actuator cage that accommodates thicker resin coverage, improving long-term durability and protection for both the switch and surrounding components during the potting process.
The design also supports surface-mount technology (SMT) compatibility, IP67 environmental sealing, and is rated up to 1 million cycles. Its mechanical construction ensures alignment during potting, reducing process variability while supporting efficient automated assembly.
As EV platforms increasingly adopt potting to enhance system longevity, especially in mission-critical subsystems, components that support full encapsulation without compromising performance are becoming essential. The KSC PF Series provides engineers with a switch that aligns with this trend while maintaining durability and compact design standards.
