Siemens Group Switch 5TE8142 2-Pole 16A Changeover DIN Rail

In control and distribution panels, switching between two circuits often requires a compact, reliable device that fits standard DIN rails. The Siemens 5TE8142 group switch solves this by providing a 2-pole changeover contact in just one module width, making it ideal for space-constrained installations.

Who is it for

Electricians and panel builders who need a manual changeover switch for lighting groups, small motors, or control circuits in residential and commercial distribution boards.
