Description

Technical Field

[0001] This utility model relates to the field of foot switch technology, specifically to a wireless medical foot switch structure. Background Technology

[0002] A foot switch is a switch that controls the on / off state of a circuit by stepping on it. It is used in control circuits where the hands cannot reach, allowing for operation without the aid of the hands. A simple foot switch essentially has a built-in limit switch; when the foot provides a signal, the switch is activated. Foot switches are widely used in medical devices, stamping equipment, welding equipment, textile equipment, printing machinery, and other fields.

[0003] With the continuous development of technology, various fields have increasingly higher requirements for the diversified connection mechanisms of foot switches. However, most existing foot switches are single or double-gang switches. The existing single-gang foot switches have some shortcomings in structure: existing single-gang foot switches generally have a power cord and a connection cord to the equipment, which requires plugging in the power supply and equipment connection cords during use. These cords can sometimes get tangled in the foot, making them inconvenient to use. Moreover, due to unreasonable structural design, existing single-gang foot switches have poor waterproof performance and are not suitable for the medical industry, resulting in poor practicality.
