Product Overview
The 1F Series is a miniature panel‑mount toggle switch that combines a distinctive red flame‑retardant base with a precision metal toggle lever, embodying the reliable aesthetics of industrial‑grade switching in a compact footprint. The switch features a classic rocker‑type toggle mechanism, with the lever snapping cleanly among three stable positions. Each actuation is accompanied by a crisp mechanical detent click, allowing operators to confirm the switch status without visual inspection. From precision control panels on instruments and meters to compact chassis in communication equipment, the 1F Series delivers industrial‑grade switching performance in a miniaturized form, making it an indispensable control hub in high‑density electronic devices.
Technical Parameters
Key Features
1. Miniature footprint, industrial‑grade capability：
Delivers high current‑carrying capacity within an extremely small mounting space, rated up to 3A @ 250VAC / 6A @ 125VAC. Small size does not mean limited performance—the 1F Series meets the dual demands of space and performance in industrial control circuits with its compact design.
2. Metal toggle lever trio, each with a distinct feel：
Available in round, flat, and long handle styles to suit different operating scenarios: the round type is ideal for quick blind operation, the flat type allows precise fingertip actuation, and the long handle provides greater leverage and enhanced feedback. One base, countless human‑machine interface experiences.
3. Panel + PCB dual mounting – rock‑solid stability：
A nickel‑plated brass threaded bushing combined with a metal locknut ensures secure front‑panel installation; the bottom straight‑pin leads are soldered directly through the PCB, forming a mechanical anchor. This dual‑fixation structure effectively resists pulling forces from cable connections and equipment vibration, eliminating any risk of loosening.
4. Red flame‑retardant armor – safety at a glance：
The base is molded from UL 94 V‑0 rated flame‑retardant engineering plastic, which self‑extinguishes without spreading in the event of fire. The iconic red color not only enhances brand recognition but also serves as a visual declaration of safety commitment—amidst dense circuit boards, critical control points can be instantly located at a glance.
5. Flick to know – status instantly recognizable：
The tilt angle of the rocker‑style toggle lever intuitively corresponds to the ON/OFF status, with the three positions (up/center/down) clearly distinguishable. In noisy industrial environments or in dimly lit equipment interiors, operators can accurately determine the switch state by touch and angle alone—no misjudgment, no hesitation.
