T Series Subminiature Toggle Switches Datasheet

Category: CK Components, Electronics, Switches

Overview

The T Series Subminiature Toggle Switches datasheet presents compact switches designed for hand-held telecommunications, instrumentation, and medical equipment. These switches are available in single and double pole models with both PC and panel mount options. For eco-friendly applications, RoHS compliant models are also offered.

Features and Benefits

The switches are praised for their compact size, which provides a small footprint, fitting into various designs without requiring much space. A range of models caters to different electrical needs, including versions specifically for higher contact ratings.

Specifications

Key specifications include contact ratings, with a maximum of 0.4 VA at 20 V AC or DC for B contact material, and up to 3 AMPS at 120 V AC or 28 V DC for Q contact material in TXO1 models. Other models handle up to 2 AMPS. The electrical life of the TXO1 models can reach up to 60,000 make-and-break cycles, while other models can accomplish up to 30,000 cycles. Additional ratings are detailed on page F-42 of the full datasheet. Contact resistance is below 20 mΩ initially, insulation resistance stands at a minimum of 10⁹ Ω, dielectric strength is at least 1000 Vrms, and the switches operate between -30℃ to 85℃. Solderability adheres to military and industry standards, and compatibility with bottom-wash PCB cleaning processes is ensured through an epoxy terminal seal.

Materials and Construction

Materials include glass-filled nylon and stainless steel for cases and housing, with brass elements for actuators, bushing, and switch support, and various materials for contact components, ensuring durability and reliability. Gold or silver plating over nickel ensures good electrical conductivity.

Customization and Ordering

To facilitate customization, the datasheet includes a ‘Build-A-Switch’ section allowing users to select options for their specific requirements, with additional information on pages F-38 through F-42. The datasheet provides information on switch functions, actuator types, terminations, contact materials, and sealing options to tailor switches to specific needs.

Dimensional Information and Part Number Reference

Detailed schematics and dimensional information are provided to ensure proper fit in user applications, with diagrams illustrating switch functions and terminal connections. Part numbers like T1O1SHZQE for single-pole double-throw (SPDT) and T2O1SHZOE for double-pole double-throw (DPDT) configurations are exemplified, illustrating the coding system used for order specification.

Note

All specifications and materials mentioned are for switches with standard options, and the datasheet encourages consulting with Customer Service Center for specific and custom switches.
