Siemens 3SB3500-0AA51 Push Button Contact Block

Product Description

The SIEMENS 3SB3500-0AA51 is a push button contact block designed for use in industrial control panel applications. Contact blocks serve as the switching element within a push button assembly, making or breaking a control circuit when the operator actuates the button. This block mounts directly to a compatible push button operator body and connects to the control wiring circuit behind the panel face. Electricians and industrial controls technicians install these components during new panel builds and when replacing worn or failed switching elements in existing assemblies.

This contact block is suited for use in industrial environments where reliable, repeatable switching is required. Typical applications include motor control stations, machine control panels, and operator interface assemblies found in manufacturing, process control, and utility settings. The compact form factor allows installation in space-constrained enclosures and control panels.
