Switch element, in particular for use by blind person or person with severely reduced visual perception, comprises reference pin

摘要

The switch is designed as a control button (1) protruding from a housing accommodating an electrically operated mechanism. When the button (1) is pushed down a reference pin (2) positioned beside the button (1) is lifted by the mechanism and vice versa. In a second version two reference pins (2) are present at the device, facilitating an indication of four different conditions by two raised pins (2), two lowered pins (2), or one of the two pins (2) lifted individually.
