Overview
The ‘T Series Subminiature Toggle Switches’ datasheet offers detailed information on a line of compact toggle switches designed for hand-held telecommunications, instrumentation, and medical equipment. This line features both single and double pole switch models with PC and panel mount options, and certain models comply with RoHS standards.
Features and Benefits
The T Series switches are lauded for their compact size, providing a small footprint suitable for various applications. Users can select from RoHS compliant options, ensuring adherence to environmental and health standards.
Specifications
The switches offer diverse contact ratings, with models using ‘B’ contact material having a maximum of 0.4 VA at 20 V AC or DC, while ‘Q’ material in TXO1 models can handle 3 AMPS at 120 V AC or 28 V DC. Other models sustain up to 2 AMPS under the same conditions. They boast an electrical life of 60,000 cycles for TXO1 models and 30,000 cycles for others, with contact resistance initially below 20 mΩ. Insulation resistance is greater than 10⁹ Ω, and they can endure dielectric strengths of 1000 Vrms at sea level. Operating temperature ranges from -30°C to 85°C, and solderability conforms to MIL-STD-202F method 208D and EIA RS-186 E.
Materials
Materials used include glass-filled nylon in the case, chrome-plated brass for the actuator, and stainless steel for the housing, with options detailed in Section N of the full document. Copper alloy with gold or silver plating is used for contacts, dependent on the specific model.
Build-A-Switch
The datasheet guides users on customizing their toggle switches using a ‘Build-A-Switch’ feature, which involves choosing options for switch function, actuator, terminations, and contact material from a selection listed on pages F-38 to F-42 of the document. Terminations fit various assembly processes, with models compatible with bottom-wash PCB cleaning methods.
Switch Function and Markings
Different models provide a range of functions such as SPDT and DPDT in various ON, OFF, and MOM (Momentary) configurations. The datasheet shows schematic diagrams and defines connected terminals’ position for each switch function. C&K markings are found on the opposite side of the switches, ensuring easy identification. Terminal numbers and models T101 to T211 are referenced for user convenience.
Additional Information
Important to note, specifications and dimensions are subject to change, and the datasheet directs users to cek-components.com for updates. For specific requirements not shown in the catalog, customers are encouraged to consult the Customer Service Center.
