Safety/position switches LS...-ZB and LS-ZB are used on centrifuges, motor and gearbox covers, presses, etc.. If the protective guard is opened, they disconnect the power and in so doing, remove the danger. LS 0-ZB and LS 4-ZB comply with EN 1088 "Interlocks with and without mechanical securing action". The selection of the necessary protective device is thus simplified. All safety position switches also fulfil the demands for use in safety circuits by their use of positively driven switching elements and positively opening contacts.

Equipped with double-break contacts, they are also suitable for use in the configuration of redundant safety circuits. The switches featuring double break contacts are suitable for use with electronic devices in accordance with IEC/EN 61 131-2, enabling the safe exchange of information with any controller.
