AI Technical Summary

⚠Technical Problem

Existing technology switches rely on the closing and opening of physical contact points to achieve circuit conduction and disconnection, which leads to the gradual accumulation of contact wear and low functional stability.

⚗Method used

A non-contact control assembly using a beam emitting unit and a beam receiving unit is employed. The optical path of the beam is changed by the light guide to realize the emission of different control signals, and a second control signal is generated by the magnetic induction element to avoid wear of the contact points.

🎯Benefits of technology

It significantly improves the functional stability and reliability of the switch, has a faster response speed than traditional mechanical switches, and is more durable and reliable than traditional mechanical switches.

Abstract

This utility model provides a switch and a flashlight. The switch includes: a mounting base; a movable component, which includes a movable part, and a light guide structure is provided at one end of the movable part facing the mounting base, the light guide structure including at least two light guide parts; a control component, which includes a beam emitting unit and a beam receiving unit, the beam receiving unit including at least two beam receiving parts; a housing, on which multiple magnetic induction elements are provided; and an annular adjusting element, which is sleeved on the housing and can rotate relative to the housing, and the annular adjusting element is provided with two magnetic elements, two adjacent magnetic induction elements forming a sensing unit. The technical solution of this utility model can solve the problem that existing switches rely on the closing and opening of physical contact points to realize the conduction and disconnection of the circuit. Due to frequent pressing, wear gradually accumulates between the contacts, and may even completely wear down and lose the conduction ability, resulting in low functional stability.
