Single Plug Key / Switch
Technical Specifications:
- Type: Single-pole, single-throw (SPST) switch
- Material: High-quality insulating base (typically bakelite or plastic) with brass or copper contacts
- Operation: Circuit is completed when the plug is inserted and interrupted when removed
- Current Rating: Typically low-voltage applications (e.g., up to 10A at 250V)
- Mounting: Tabletop or panel-mounted design
Description
A Single Plug Key is a simple electrical switch used in laboratories and educational setups to open or close an electrical circuit. It consists of a base, a removable plug, and contact points that complete the circuit when the plug is inserted. This device is primarily used in physics experiments and electrical circuit demonstrations to control the flow of current in a safe and effective manner.
Applications:
- Used in educational and laboratory experiments to demonstrate circuit principles
- Applied in physics and electrical engineering studies for current flow control
- Utilized in testing setups and temporary circuit connections
- Common in basic electrical training kits and instructional demonstrations
