Finger security

from Wikipedia, the free encyclopedia

Finger safety is a property of technical devices or other devices.

A device is finger-safe if it is impossible for a child or a normal adult to put their own fingers in dangerous areas of the device in question. The danger can be, for example , parts under electrical voltage or fast moving parts. Dangers that could potentially cause life-threatening injuries.

For example, different types of plugs are finger- safe ( German Schuko plug type F , British plug type G , Swiss SEV-1011 system according to the 2011 standard, but not according to the old 1998 standard).

  • The Schuko is finger-safe because of the recess in front of the contacts.

  • The BS 1363 plug shown here has insulated contact pins at the lower end to increase finger safety.

  • The plug type D shown here is not finger-safe due to the uninsulated contact pins and the flat design of the socket.

  • SEV-1011 connector, at the top according to the 1998 standard (not finger-safe), at the bottom according to the 2011 standard (finger-safe). Sockets without protective collars (not finger-safe), prohibited since 2017
