Abstract
A switching pad or plate having electroinsulating flat bodies arranged essentially in parallel to one another, to which at least one current-conducting contact path is assigned which has disconnecting switches disposed in series and are actuated by pressure on one of the flat bodies. Contact pins are assigned to the disconnecting switches which contact pins subjected to spring force, rest against the contact path by a contact head. The contact pins are firmly connected at the end facing away from the contact head with one of the flat bodies and each contact pin is movably held in a guide which is formed by an insulating flat body.
Claims7
A switching pad comprising:
- electroinsulating flat bodies arranged substantially in parallel to one another;
- at least one current-conducting contact path arranged between said flat bodies;
- a plurality of switches coupled in series and spaced apart along said current-conducting path and being actuated to interrupt said current conducting path;
- wherein said switches are formed by contact pins, each of said contact pins having a contact head and an end facing away from the contact head;
- and
- a spring providing a spring force to bias said contact pins such that their contact heads electrically contact the contact path to form a closed current-conducting path, wherein the contact pins are firmly connected by the end facing away from the contact head with one of the flat bodies, and wherein at least one of said flat bodies forms an insulating guide in which the contact pins are movably held;
- whereby pressure on one of said flat bodies actuates at least one of said switches by countering said spring force to open the electrical contact between the contact head of the contact pin and the contact path.
