These 100PCS/LOT 8x8x5MM 4 Pins Conductive Silicone Soundless Tactile Tact Push Button Switch Selfreset are compact tactile switches designed for quiet, reliable actuation in small electronic panels and devices. With a conductive silicone contact and a selfreset design, they provide a clean, lownoise tactile feel while returning to the resting position after each press. Key benefits Quiet operation: soundless tactile feedback suitable for noisesensitive environments such as media devices, keyboards, and control panels. Reliable actuation: conductive silicone contacts deliver stable electrical performance with repeated use. Selfreset mechanism: the switch returns to its original position automatically after release, ensuring consistent operation. Compact footprint: 8x8x5 mm size with a fourpin configuration fits into tight PCB layouts and compact enclosures. Costeffective bulk supply: 100 pieces per lot, ideal for projects, prototypes, and production runs. Key attributes Functionality: tactile push button switch, selfreset, conductive silicone actuation Pins: 4 pins for straightforward PCB mounting Size: 8 mm x 8 mm x 5 mm Material: conductive silicone construction Operation: soundless/tactile feel Quantity: 100 pieces per lot Compatibility: suitable for standard PCB circuits and compact electronic assemblies What makes it unique Conductive silicone technology provides a quiet, reliable actuation with a lowprofile silhouette. Selfreset design ensures a consistent to the resting state after each press, improving user experience in handheld devices and control panels. Fourpin configuration offers a stable mounting option for standard PCB layouts while maintaining a compact 8x8 mm button size. Applications and use cases Remote controls and keypad input panels in consumer electronics such as set boxes, audio/video equipment, and small appliances DIY electronics and hobby projects, including compact keyboards, control panels, and educational kits Prototyping and production of compact devices requiring a silent, tactile push button with a fourpin PCB footprint How to use Align the four pins with the corresponding PCB pads. Solder each pin securely to ensure good electrical contact and mechanical stability. Ensure the button housing sits flush with the panel or enclosure surface for reliable actuation. Operate the switch by applying light, firm pressure to the tactile surface; the button will be selfreset after release. Notes These switches are designed for lownoise, tactile operation and should be used within the electrical and mechanical limits of the intended PCB design. Suitable for applications where quiet input is preferred and the compact 8x8 mm footprint is advantageous. This product provides a practical, consistent tactile switch option with a quiet feel, suitable for a wide range of compact electronic applications.
