General Electric CR104PSG21B1 Selector Switch

General Electric CR104PSG21B1 is a position-maintained selector switch that latches in the selected position until it is manually changed. It ships with a D21 contact block, providing the fixed contacts actuated by the switch position for routing power or signals in a control circuit. As a GE component, the CR104PSG21B1 pairs a maintained operator with the D21 contact block to support repeatable, deterministic switching behavior in electrical panels and automation wiring. The maintained action means the chosen setting stays in effect without holding the switch, which can simplify status indication and reduce actuation requirements in multi-step control schemes. This configuration offers a compact, modular interface that integrates with GE’s broader line of selector switches and standard wiring practices, enabling straightforward installation and reliable circuit selection across multiple control applications. The CR104PSG21B1 designation identifies a specific GE configuration that couples a maintained operator with the D21 contact block for consistent, repeatable operation. Ideal uses include manual mode selection, routing between preferred circuits, and providing a clear control input within mechanical or electrical control systems.
