This document provides specifications and dimensions for ITT Cannon's B-24 Tactile Switches, including different actuating forces and contact plating options. The switch features high shear force, easy pick and place, rubber or hard plastic actuator, press fit or snap fit caps, IP57 rating, and RoHS compliance. It is suitable for telecommunications, computer products, instrumentation, and power supply applications.
The KT Series right‑angle sealed tactile switches are designed for surface‑mount technology with a high shear force and a compact actuator. Features include a gullwing terminal, IP57 protection, and RoHS compliance, making them suitable for telecommunications, computer products, instrumentation, and power supplies.
The datasheet lists electrical and mechanical specifications such as a 1.0 VA contact rating, 100 000 make‑and‑break cycles, and an operating temperature range of –40 °C to 90 °C. Ordering information describes a build‑a‑switch concept with selectable actuator types, mounting brackets, and button options.
