SS9MS-11A1A0A

The SS9MS-11A1A0A from Danaher is a high-performance surface mount slide switch in the Timers and Controllers series designed for precision industrial automation tasks. This robust switch features a SPDT circuit configuration and a maximum Contact Rating of 0.4VA max @ 20V AC/DC, ensuring reliable signal control. Constructed with Gold contact material and a low Contact Resistance of 50 mOhm Max, it delivers exceptional conductivity and longevity. With a compact Mounting Type of Surface Mount and Termination Style of Gull Wing, the SS9MS-11A1A0A balances a small footprint with sturdy installation options. Compatible across a broad Operating Temperature range of -40°C ~ 85°C, it thrives in demanding environments.

Offering advanced technical capabilities, this switch provides two switching positions (Number Of Positions: 2) with an ON-ON Switch Function and smooth Slide Switching Type operation. The Setting Accuracy of ±0.5% guarantees repeatable actuation thresholds for consistent performance. Its Actuator Type is a standard top-mounted design with Actuator Orientation set to Top Actuated, delivering accessible manual or automated control. An impressive Insulation Resistance of 100 MOhm Min and dielectric strength endure high-voltage differentials, while the Contact Rating supports both control and low-power signal applications.

Operationally, the SS9MS-11A1A0A excels in high-cycling scenarios thanks to its robust mechanical design and durable actuation components. The gold-plated contacts resist corrosion and maintain low contact resistance throughout the device’s lifecycle. Surface mounting simplifies PCB assembly and reduces installation time, while the gull wing termination enhances solder joint reliability. With defined actuation effort and precise switching thresholds, this slide switch minimizes bounce and delivers clean signal transitions.

Integration into control modules, instrumentation panels, and compact industrial controllers is seamless, as the SS9MS-11A0A’s gull wing leads interface directly with automated pick-and-place lines. Its narrow footprint and resilient configuration support space-constrained PCBs in automotive, communication, and factory automation systems. Paired with Danaher’s Timers and Controllers family, it ensures synchronized timing and switching operations for complex process control applications.
