1. How does a signal switch work?
When a signal switch is activated, it changes the path of the signal. In simple mechanical switches, this usually means connecting or disconnecting between physical contact points. For electronic switches, such as MOSFETs or BJTs, the on and off states are controlled by applying voltage or current to achieve the conduction or blocking of signals.

2. What is the difference between power switches and signal switches?
The difference between power switches and signal switches is mainly the energy level they handle. Power switches are designed to carry larger currents and powers, and are usually used to directly control power supplies; while signal switches handle smaller currents and are mainly used to control logic levels or routing of small signals.

3. What is the use of a decoder?
The role of a decoder is to restore the encoded data to the original information or trigger the corresponding function based on the input code. For example, a BCD to 7-segment decoder is a common decoder used to convert binary coded decimal numbers into signals that drive a seven-segment display.
