This document is about the specifications of APEM's pushbutton switches, including product model, size, rated voltage, rated current, etc.
The APEM catalog lists a wide range of pushbutton switches, including tiny, miniature, sub‑miniature, and washable series. Each series is described with electrical ratings, mechanical dimensions, material options, and ordering information.
The document also details packaging formats such as tape‑and‑reel for surface‑mount devices, recommended soldering processes, and cleaning procedures for washable switches. Technical data like contact ratings, insulation resistance, and operating temperature are provided for designers and engineers.
