Mercury Switch - Wikipedia
A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit. There are several different basic designs (tilt, displacement, radial, etc.) but they all share the common design strength of non-eroding switch contacts. ... Read Article
Motor Controller 29 - VEX Robotics
The VEX Motor Controller 29 uses a standard PWM signal (like that originating from the 3-wire ports on VEX Microcontrollers) to drive a VEX 2-Wire Motor. Note: We recommend using no more more than one (1) 3-Wire extension cable in between the Motor Controller 29 and a VEX Microcontroller. For longer extensions, use 2-Wire extension cables in ...
