Feature → Business Impact → Application: Single pole double throw (SPDT) configuration reduces component counts in control circuits, delivering a cleaner wiring harness and faster fault isolation in machine panels. This translates to lower assembly time and reduced maintenance overhead during lifecycle management. Application: control panels in industrial automation where a single control signal must select between two outputs, such as valve actuation or motor control in equipment bays. Feature → Business Impact → Application: 20A current rating at 125VAC and 10A at 250VAC supports common control circuits and lighting/actuation loads, enabling designers to use one switch for multiple voltage environments without compromising safety or performance. Application: power distribution and control logic in OEM equipment where versatility matters. Feature → Business Impact → Application: screw mounting provides a secure, vibration-resistant fit, reducing loosening risk in rugged environments; installation is straightforward with standard tools. Application: panel fabrication across manufacturing lines with frequent start-stop cycles. Feature → Business Impact → Application: nickel finish enhances wear and corrosion resistance, extending service life in environments with frequent switching and exposure to contaminants. Application: front-panel controls in manufacturing cells and process equipment. Feature → Business Impact → Application: 1P 2T On-On configuration simplifies user operation and minimizes miswiring risk; data sheet SWTG12-OO confirms electrical characteristics for engineering documentation. Application: control interfaces in automation cabinets and machinery where precise two-position signaling is critical. Feature → Business Impact → Application: standard packaging and 4 EA per carton support efficient logistics and inventory planning; consistent sourcing aids maintenance planning. Application: spare parts strategy for multi-site installations.

FAQs
This toggle switch uses screw mounting and is designed for panel integration. It is a 1P SPDT device wired in single-pole, double-throw configuration, suitable for standard control panels. When selecting a cutout, ensure the chassis accommodates a compact footprint and provides secure fasteners to resist vibration. The data sheet SWTG12-OO can guide mounting tolerances and installation best practices.
The 7TBA008940R0110 is a 1P, 2T SPDT toggle switch with On-On functionality. It is rated for 20A at 125VAC and 10A at 250VAC, making it suitable for common control circuits and auxiliary loads in industrial panels. It uses a nickel finish for durability and is designed for screw-terminal mounting in standard control cabinets.
Yes, for typical control-panel tasks, the switch’s SPDT On-On configuration supports reliable signaling between two circuit paths, and the nickel-plated surface offers wear resistance against frequent actuation. It is well-suited for applications like valve control, fan/blower circuits, and other supervisory controls within validated voltage ranges.
The provided data references the SWTG12-OO datasheet and related classifications, including UNSPSC 39122211 and WEEE status. Specific certifications such as CE or UL are not listed in the dataset for this model; customers should consult the datasheet and regional compliance requirements to confirm applicable certifications before deployment.
Anticipate low maintenance due to the nickel finish and robust mechanical design. The switch is designed for screw mounting in control panels, enabling straightforward replacement if the unit wears or fails. Maintain spare inventory for 1P SPDT switches of this rating to minimize downtime during routine panel upgrades or fault remediation.
