Tactile Switch SPST-NO Top Actuated Surface Mount The B3FS-1002P is a compact, surface-mount tactile switch designed for low-profile input applications. It provides a momentary contact mechanism with a distinct tactile feedback, making it suitable for user interface controls in consumer electronics, industrial devices, and compact embedded systems. The switch features a sealed construction for improved reliability and is optimized for automated PCB assembly processes. Mechanical Characteristics Mounting Type: Surface Mount (SMD) Actuator Style: Top push Actuator Height: Low profile Outline: Rectangular compact body Terminal Type: Gull-wing terminals Sealing: Dust-resistant (sealed construction) Electrical Characteristics Switch Type: Single Pole Single Throw (SPST) Contact Configuration: Normally Open (NO) Rated Voltage: Low voltage DC applications Rated Current: Suitable for signal-level switching Contact Resistance: Low initial contact resistance Insulation Resistance: High insulation resistance between terminals Operating Characteristics Operating Force: Standard tactile force (manufacturer-defined variant) Travel Distance: Short stroke tactile action Operating Life: High durability for repeated actuation cycles Bounce Time: Minimal contact bounce for reliable switching Environmental Characteristics Operating Temperature Range: Wide operating range suitable for consumer and industrial use Storage Temperature Range: Standard electronic component storage conditions Humidity Resistance: Designed to withstand typical ambient humidity conditions Material & Construction Actuator Material: High-strength polymer Housing Material: Heat-resistant plastic Contact Material: Metal alloy with surface plating for durability Terminal Finish: Solderable finish compatible with reflow soldering Packaging Information Packaging Type: Tape and reel Assembly Compatibility: Fully compatible with automated pick-and-place and reflow processes Applications Consumer electronics (keypads, remote controls) Industrial control panels Portable devices Embedded system user interfaces Wearable and compact electronics #commonpartslibrary #switch #tactile

The MAX485 TTL to RS-485 Interface Module allows MCUs to use the RS-485 differential signaling for robust long distance serial communications.

MPN: FH34D-4S-0.5SH(50) Manufacturer: Hirose Electric Part Type: FFC/FPC Connector / Right-Angle SMT ZIF Connector Description: 4-position 0.5mm pitch SMT right-angle/back-flip FPC connector used as the board-side connector for the TDK PowerHap 1204H018V060 piezo haptic actuator FPC. The actuator FPC connects to this connector, with only pin 1 and pin 4 used for the high-voltage piezo actuator connection to maintain creepage/clearance distance. Connect the actuator positive terminal to the haptic driver's high-voltage output and the negative terminal to the driver return/GND according to the PowerHap FPC polarity.
