Every switch needs an actuation device. A person can be this device such as turning on a light or coffee maker. Upon doing so you push a button or move a lever to make the switch switch. In the automation world, the actuation is done electrically; a coil or solenoid. However, this acuation also has to be triggered by a sensor. This gives us the automatic switch needed for automation and control.
Sords Electric has switches that use light, sound, temperature, flow, magnets, current, voltage, pressure, and even hands to switch the switch. Names for these types of switches are photoelectric switches, laser switches, ultrasonic switches, temperature switches, flow switches, proximity switches, GFCIs or current switches, contactors and relays, pressure switches and control mats, and manual disconnect switches.
In further posts we can discuss each type of switch and how they function.
