TE Connectivity / Potter & Brumfield Alcoswitch Sealed Tactile Switches
TE Connectivity's / Potter and Brumfield Alcoswitch Sealed Tactile Switches are high-quality electromechanical components that deliver reliable tactile feedback and environmental protection. These switches feature an IP67-sealed construction for protection against dust, water, and other contaminants. The Alcoswitch switches offer multiple options for actuation force (light to heavy press feel), actuator height and orientation (vertical or right-angle), and actuator travel distance. These tactile switches provide a high degree of customization, enabling integration into consumer-facing and industrial-grade interfaces while maintaining a compact footprint and reliable electrical performance. Typical applications include automotive, remote controls, handheld devices, earbuds, wearables, operator panels, automation systems, medical devices, home appliances, server equipment, switches, and routers.
