3. Understanding Switch Basics
Before diving into specific switch models, it’s essential to understand how switches work.
A switch is an electrical component that opens or closes a circuit, allowing current to flow or stop. The simplest form is a single-pole, single-throw (SPST) switch, but industrial environments often use more complex types like double-pole or multi-throw configurations.
Key Parameters Include:
- Pole and Throw: Defines how many circuits can be controlled and in how many directions.
- Current and Voltage Ratings: Determines how much power the switch can safely handle.
- Actuation Type: Momentary (returns automatically) or maintained (stays in position).
- Environmental Conditions: Sealing (IP ratings), vibration resistance, and temperature tolerance.
