Overview

The TS40-66-38-BK-260-SMT-TR is a surface-mount SPST-NO tactile switch designed for compact user interface applications. It features a 6.00mm by 6.00mm footprint and a 3.8mm height, providing a reliable momentary off-on function with a tactile feedback force of 260gf. The switch is rated for low-power signal switching up to 12V DC and 50mA.

Why Choose This Part

This switch offers a high 260gf operating force for a crisp, firm tactile response that helps prevent accidental actuation. Its gull-wing SMT leads allow for easy automated pick-and-place assembly and inspection, while the 50mA current rating is well-suited for direct microcontroller GPIO input.

Applications

Consumer Electronics
Ideal for push-button interfaces in home appliances, office equipment, and handheld devices.
Industrial Control Panels
Provides tactile feedback for membrane-style control interfaces and system reset buttons.
Diagnostic Equipment
Suitable for mode selection or user input on PCBs where space is limited and SMD assembly is required.

Getting Started

When integrating this switch, ensure the PCB land pattern accounts for the 6.4mm lead pitch. Engineers should implement hardware or software debouncing, typically using a 10nF to 100nF capacitor or a software timer, to manage the mechanical contact bounce common in tactile switches. The switch is rated for operation between -20 and 70 degrees Celsius and is supplied in tape and reel format for high-volume production.
