The C&K PTS635 series 3.5mm tactile switches are designed for applications requiring a compact and reliable momentary action switch. These switches feature a variety of options including different actuation forces (130g, 200g, and 260g) and actuator heights to accommodate diverse design requirements. Constructed with materials like nylon and phosphor bronze, they offer durability and consistent performance. Common applications include consumer electronics, instrumentation, computer products, and industrial controls. The switches are RoHS compliant and available in both through-hole and surface mount configurations, simplifying integration into various PCB designs. The easy build-a-switch concept allows for customization to meet specific application needs.
