SWITCH

---

A device used to open or close an electrical circuit. Also an electronic device used to alternate between two input SIGNALs, in some cases the rate of switching being controllable by a PULSE or triggering voltage.

Rapid switching of the on/off variety is called chopping, and can be effected by using a voltage-controlled amplifier (VCA) triggered by a PULSE WAVE or SQUARE WAVE.
