Range of application
Safety foot switches are mounted on machines and plants as enabling switches in cases where operation using the hands is not possible and an emergency-stop function in case of an hazardous situation is required.
Design and mode of operation
All safety foot switches are mounted with a shield to protect against unintentional operation. When the foot pedal is actuated to as far as the pressure point, the NO contact is closed. If, in case of danger, the pedal is actuated beyond the pressure point, then the positive break NC contact is opened and mechanically latched. Reset operation is carried out by means of a push-button. The function principle of all safety foot switches is also shown in the drawing below. The safety foot switches conform to IP 65.
All safety foot switches bear the CE mark according to the Machinery Directive 2006/42/EC.
