100 pieces of tactile DIP push button switches, red cap, 6 x 6 x 3.1 mm, vertical 4 pin, copper head, waterproof Key benefits Reliable tactile feedback for clear on off input when you press a button. Ideal for menus, user interfaces, and manual controls. Waterproof protects the contact area from splashes and debris, extending serviceability in workshop and light industrial environments. Copper head contact provides good conductivity and stable signal transfer for consistent performance. Pack of 100 provides spare parts for production runs, repairs, or multiple prototypes, reducing downtime. What this switch does and why you need it Momentary tactile push button designed for through hole PCB mounting in a vertical orientation. The 4 pin footprint gives firm mechanical support and helps prevent wobble during repeated use. Compact 6 x 6 x 3.1 mm red actuator makes it easy to place on dense boards while remaining easy to find and press. Suits projects and repairs where reliable manual input is required, from small consumer electronics to control panels. Important attributes Quantity: 100 pieces Dimensions: 6 x 6 x 3.1 mm (actuator size) Button color: red Mount style: DIP vertical, through hole, 4 pins for stable mounting Contact material: copper head Function: tactile, momentary push button Environmental: waterproof design to guard the contact area from splashes and dust Practical use scenarios Prototype and development projects: integrate into PCB layouts for microcontroller interfaces, breadboarded prototypes, and lab test rigs where compact, repeatable input is needed. Equipment and maintenance: worn or damaged momentary switches in consumer electronics, toys, or industrial controls without redesigning the PCB. Control panels and user interfaces: populate small control boards for appliances, kiosks, and instrumentation where a low profile, tactile button is preferred. Why choose this pack Ready quantity for small production or multiple jobs Consistent size and footprint for straightforward PCB layout and assembly Robust mounting and copper contact for dependable electrical performance Includes 100 individual red, 6 x 6 x 3.1 mm vertical 4 pin tactile push button switches with copper head contacts and waterproof design.
