Keys and Switches(6)

Keys and Switches covers 6 physics-lab circuit accessories — plug keys, tapping keys, a reversing key/commutator and a jockey model — used to make and break circuit connections in electricity experiments. These are small but essential components for wiring up circuits in physics practicals at school and college level, and LabEquip supplies them to physics labs alongside the main Electrical and Electronics range.

The Range: What’s in Keys and Switches

Basic circuit-switching is covered by the Single Circuit Plug Key and the Four Contact Plug Key for circuits needing multiple connection points. Timed-contact experiments use the Physics Lab Tapping Key, while current-direction experiments use the Reversing Key Commutator. The Pencil Jockey Physics Model is used for sliding-contact experiments such as potentiometer and metre-bridge practicals, and the Electrical Switching Plug Key rounds out the range for general circuit-switching needs.

Category FAQ

What is included in the Keys and Switches category? Plug keys, a tapping key, a reversing key/commutator and a jockey model for physics circuit experiments — see individual product pages for exact specifications.

Which key is used for potentiometer or metre-bridge experiments? The Pencil Jockey Physics Model is the sliding-contact component used in these experiments; the plug and tapping keys are used for general circuit switching rather than sliding contact.
