A push-button switch is used to input data to a register. The output of the register is erratic. What could be causing the problem?

The power supply is probably noisy.
The switch contacts are bouncing.
The socket contacts on the register IC are corroded.
The register IC is intermittent and failure is imminent.

Correct Answer: The switch contacts are bouncing.
