Problems solved by technology

[0004] However, the above-mentioned foot control switch has a considerable crisis in practicality. When operators such as doctors and nurses are in a busy environment or in a state of mental distress, they often neglect the position of the foot control switch, causing the operator to use both hands. It may be still adjusting the work, and suddenly step on the switch, thus causing accidents, and even threatening the lives of patients and operators in severe cases

Abstract

The invention discloses a foot control switch with a security mechanism. The foot control switch comprises a base body, a circuit board, a pedal device and a locking device, wherein the circuit board is accommodated in the base body, the pedal device is installed on the base body, the locking device is close to the pedal device, and the pedal device is electrically connected with the circuit board through the locking device. When the locking device and the pedal device are pressed, the circuit board and the pedal device are electrically connected. Therefore, the circuit board and the pedal device are not connected to perform follow-up drive signal output until the pedal device performs an unlocking action through the locking device, the foot control switch is further prevented from being touched mistakenly, and accordingly the safety of the foot control switch in use is improved.

Description

technical field [0001] The invention relates to a switch control structure, in particular to a foot control switch with a safety mechanism. Background technique [0002] In general medical equipment, hospital beds or diagnosis and treatment chairs must adjust the lifting or tilting angle to match the patient's body shape or needs, so as to make the patient comfortable. However, because doctors use both hands to operate hand tools for medical treatment, they are all equipped with a foot control switch based on the convenience of switch control and the convenience of treatment. [0003] The traditional foot switch includes a switch box and a pedal. A switch is installed inside the switch box; the pedal has an automatic return plate. switch to transmit a driving signal. In this way, by stepping on the foot switch, the hospital bed or the diagnosis and treatment chair receives a driving signal, thereby controlling the elevation and inclination of the hospital bed or the diagno...
