Dubois Raymond Keys from JaincoLab are make-and-break electrical switches that deliver a single, controlled stimulus, typically from an induction coil, to a nerve-muscle preparation so the resulting twitch or nerve response can be observed and recorded. The JA-DRK-2400 is a bench-mounted mechanical key with connecting terminals for wiring into an induction-coil circuit, used in physiology and electrophysiology practicals in teaching labs and medical and veterinary colleges.

What is a Dubois Raymond Key?

A Dubois Raymond Key is a make-and-break electrical switch used in classical electrophysiology teaching setups to deliver a single, controlled electrical stimulus — typically from an induction coil — to a nerve-muscle preparation, so that the resulting muscle twitch or nerve response can be observed and recorded. It is one of the standard apparatus items used alongside induction coils in physiology practicals on nerve and muscle excitability.

Frequently Asked Questions

What is the difference between a Dubois Raymond Key and a Simple Key?
A Dubois Raymond Key is a specific make-and-break key historically used with induction coils in nerve-muscle physiology, while a Simple Key is a more basic circuit-make key used generally to control stimulus delivery in physiology experiment setups.
