Frequently Asked Questions
What Are the Assembly Requirements for the TS-1187A-B-A-B in a Standard SMT Pb-Free Reflow Production Line?
The TS-1187A-B-A-B is RoHS compliant and designed for Pb-free SMT reflow assembly. Given that tactile switches contain a plastic actuator housing, the reflow peak temperature must be managed carefully to avoid deformation of the switch body. Standard SMD tactile switches in this class are typically rated to withstand peak reflow temperatures of 260°C for a maximum of 10 seconds, consistent with IPC/JEDEC J-STD-020 Class 3 profiles. Avoid excessive pre-heat dwell times that could soften the actuator stem. The standard full-reel packaging of 4,000 pieces ensures efficient tape-and-reel SMT placement and prevents manual handling during high-volume assembly.
How Does the 160gf Actuation Force of the TS-1187A-B-A-B Compare to Common Tactile Switch Options, and What Applications Is It Best Suited For?
The 160gf actuation force places the TS-1187A-B-A-B in the medium-to-firm tactile range. Light-touch switches typically range 50–100gf, while 160gf provides more deliberate actuation — ideal for reset buttons, test points, mode selectors, and any user-interface function where inadvertent activation must be avoided. The 1.5mm travel distance gives clear tactile feedback to the operator. This combination of force and travel makes the switch particularly suitable for industrial control panels, embedded system reset inputs, IoT devices, and consumer electronics where the button will be pressed with a tool or a deliberate finger press rather than a light casual tap.
What Are the Key Mechanical and Electrical Specifications of the TS-1187A-B-A-B Tactile Switch, and What Switch Configuration Does It Use?
The TS-1187A-B-A-B is a SPST (Single Pole Single Throw) tactile switch from XKB Connection, housed in an SMD-4P, 5.1x5.1mm package designed for surface-mount assembly. The actuation force is 160gf and the travel distance is 1.5mm, making it a medium-force, short-travel switch suitable for user-interface and reset button applications. The full package footprint measures 5.1mm × 5.1mm and the part is fully RoHS compliant. The CNHTS code is 8536500090 and USHTS 8536507000, confirming its classification as an electromechanical switch for international customs purposes.
