Practical Electronic Design for Experimenters

CHAPTER 10Electromechanical Design

Some of your designs may use electromechanical devices. This chapter covers the most common devices that include switches, relays, solenoids, motors, and servos. Most of the design effort involves understanding how the devices operate and paying attention to the specifications on each device’s data sheet. The circuits are simple, and the more common configurations are covered here.

Switches

You already know what a switch is, so I won’t elaborate other than to review that a switch is a set of manually operated mechanical contacts designed to carry electric current. There are dozens of different configurations and types. Only the most common operations and types are covered here.

Switch Contacts

There are three ...
