Siemens 3SB3501-2TA41 Selector Switch Contact Block

Product Description

The SIEMENS 3SB3501-2TA41 is a retained-contact selector switch block designed for use in industrial control panels and machine control circuits. This component provides the switching action for multi-position selector switches, maintaining contact position when the actuator is turned and held. It is built for integration into control enclosures where reliable, repeatable switching is required. Electricians and industrial control technicians install this type of device during panel builds, machine retrofits, and control system maintenance.

This selector switch contact block is suited for industrial applications including machine tool controls, conveyor systems, process control panels, and general-purpose motor control circuits. The retained-contact design holds the selected switch position without spring return, making it appropriate for maintained-mode selector configurations. It mounts to standard 22 mm selector switch bases in industrial control enclosures.
