S Series Snap-Action Switches

Schaltbau S Series Snap-Action Switches are microswitches designed for safety-oriented switching applications. The family includes various series, allowing designers to select the appropriate combination of contact configuration, actuator style, terminal option, contact material, housing material, temperature capability, and environmental protection level. Schaltbau S Series switches feature positive opening operation, a robust switching mechanism, and multiple models with self-cleaning contacts. Select variants also provide galvanically isolated contact bridges, double-break contacts, or IP67 protection. Polyetherimide (PEI) housing options are available for applications that require increased resistance to demanding operating conditions.
