Rapid safety switch and rapid safety switch system

A rapid safety switch, comprising:

• a switch housing, said switch housing having:
• six housing external sides, including a housing front side, an open housing rear side, a housing upper side, a housing lower side, a first housing side, and a second housing side;
• an operating-tool interface to be operated through one of said housing external sides;
• and
• one or more connection elements for controlling the rapid safety switch;
• an electromagnetic release mechanism configured to unlatch the rapid safety switch and a moving contact to be moved by a spring accumulator, said spring accumulator being latched in a biased position, and to be released from being latched by said electromagnetic release mechanism;
• said moving contact being movable between a first position and a second position, and wherein, in the first position, said moving contact:
• is connected electrically conductively to a fourth terminal;
• and
• is electrically isolated from a first terminal and from a second terminal and from a third terminal;
• and
• in the second position, said moving contact:
• is connected electrically conductively to the fourth terminal;
• and
• is in electrically conductive contact with the first terminal and with the second terminal and with the third terminal;
• and
• said moving contact of the rapid safety switch, upon being unlatched by the electromagnetic release mechanism, moving from the first position to the second position, and said moving contact of the rapid safety switch being configured to be moved from the second position to the first position by way of said operating-tool interface.
