Multidirectional input device, control handle, and manipulation device

Abstract

This application provides a multi-directional input device, a control handle, and a control device, including a housing, an operating body, a reset mechanism, a circuit board, and a magnetic sensing element. The operating body includes an operating main body and a protrusion disposed around the periphery of the operating main body. The operating main body includes a first end that extends from an opening into a first cavity. The protrusion is movable horizontally within the first cavity. The reset mechanism is disposed within the first cavity and elastically abuts against the protrusion. The reset mechanism is configured to reset the operating body to a starting position when at least a portion of the operating body slides within the first cavity. The magnetic sensing element includes a magnetic element and a magnetic sensor. The magnetic element is disposed in the protrusion, and the magnetic sensor is disposed on the circuit board. A gap exists between the magnetic element and the magnetic sensor. This solves the problem of short lifespan of traditional carbon film contacts.
