Snap-actionswitches I Page6

S800, S804 and S814 Series snap-action switches feature positive opening operation, which guarantees a reliable opening of NC contacts, even when welded due to short-circuits or overload currents. That is why S800 Series snap-action switches are particularly suitable for applications where safety is a prime requirement.

The snap mechanism for which Schaltbau's switches are well-renowned ensures rapid switching of high electric loads with switchesof compact design that will fit in the most confined spaces.

S820 switches add to the well proven standard series of snap-action swit­ches with positive opening operation as developed by Schaltbau with an even more ruggedised design, featuring a current-carrying capacity which is twice as high (l_th = 20 A). Consequently, the switch should be used only for higher loads.

The S820 Series switch is a Form Z circuitry SPDT-DB. Its two mechanically linked rigid contact bridges are electrically separated. Thus it is especially suited for use in automation applications where the simultaneous handling of two separate load circuits is required.
