Foot switch

Application:
Safety foot switches are mounted on machines and plants as permissive switches in cases where manual operation is not possible.

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 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. During the reset operation, the switch does not move through the switching-on point.
