A crowbar circuit is an electrical circuit used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o ), like dropping a crowbar across the output terminals of the power supply.

List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices. A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
This circuit using a Triac rather than an SCR has an additional protection against reversed polarity. However, residual reverse voltage is higher than using Si diodes or Schottky diodes. In case of reverse voltage, the TL431 will conduct with its output protection diode. This current will eventually fire the triac.
A crossbar switch is an assembly of individual switches between a set of inputs and a set of outputs. The switches are arranged in a matrix. If the crossbar switch has M inputs and N outputs, then a crossbar has a matrix with M × N cross-points or places where connections can be made.
The British "crowbar", five or six feet long with a chisel end, is dealt with under the American term spud bar. This "crowbar" is the American term for the thing called a jemmy in Britain. --Richard New Forest 18:42, 26 April 2008 (UTC)
