Must the medical mechanical membrane switch be anti-static

When using medical mechanical membrane switches, many people will first think of safety issues, so anti-static shielding interference is a necessary requirement for medical mechanical membrane switches. A medical mechanical membrane switch panel that can be shielded from electrostatic interference is a momentary switching device that has at least one contact element arranged on or made of a flexible substrate. This type of membrane switch keyboard is generally used in household appliances, industrial machinery, medical machinery and other products. Since the switch product is a human-machine interface operating system, the safety of the product directly affects the safety of the operator.

Static electricity will bring certain interference to people, and static electricity will cause electric shock. The electric shock caused by static electricity may occur when the human body is close to the object with static electricity, or when the human body with static charge is close to the grounding surface. Static electricity can be as high as ten thousand volts. Although static electricity sometimes does not cause too much harm, it can cause tension for users. For medical mechanical membrane switches, if the use will cause the operator's tension, this will affect the normal use of medical mechanical equipment.

The medical mechanical membrane switch keypad will not disturb people due to static electricity, it is a kind of safe membrane switch. The switching circuit system is often susceptible to electrostatic discharge interference. In order to prevent this static phenomenon, a metal ground can be configured under the switch circuit. Although the metal ground can avoid static electricity, the use of ground will increase the weight of the entire switch and manufacturing costs.
