Product overview A pack of 100 compact tactile push button switches designed for PCB mounting and small electronics. Each switch measures 3 x 4 x 2.5 mm with a white actuator and four metal pins for secure soldering. Ideal for , prototyping, and lowprofile control panels. Key benefits Ready supply for repairs and projects: 100 identical switches in one pack saves time sourcing components and ensures consistent performance across multiple units. Space saving low profile: 3 x 4 x 2.5 mm footprint fits tight layouts and lowclearance enclosures where larger switches will not fit. Reliable tactile feedback: Designed to provide a clear physical click for accurate user input in remote keys, small controllers, and custom electronics. Easy PCB mounting: Fourpin design gives stable mechanical support and straightforward solder connections for throughhole or PCB assembly. Neutral color and compact shape: White actuator blends into many designs and allows for easy labeling or overlay placement. Important attributes Quantity: 100 pieces per lot. Dimensions: 3 mm x 4 mm x 2.5 mm (height). Pin count: 4 pins for secure PCB attachment and mechanical stability. Actuator: white push button suitable for replacement keys and control panels. Construction: plastic actuator with metal terminals for electrical connection and durability in typical electronics applications. Function: momentary tactile push switch for user input and signal control. Practical use scenarios Car remote key : worn or unresponsive buttons in key fobs and remote keys where a compact, lowprofile tactile switch is required. DIY electronics and prototyping: Use these switches on custom PCBs for prototype remote controls, handheld devices, and compact sensor interfaces. Small appliance and gadget maintenance: Restore functionality to calculators, small remotes, and control boards by swapping out damaged or sticking buttons. Why choose these switches Consistent size and operation across all 100 pieces reduce variability during assembly and . Compact profile and secure fourpin mounting make them suitable for dense PCB layouts. Neutral white actuators support a wide range of design styles and replacement needs. What to check before buying Confirm the 3 x 4 x 2.5 mm footprint fits your PCB layout and enclosure. Verify the fourpin pad pattern on your board matches the switch terminals for proper soldering. Ensure the tactile switch type meets your electrical and mechanical requirements for the intended device.
