Switches are devices that allow electric current to flow when closed and prevent current flow when opened.

Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects

Temperature instruments use contact or noncontact methods to measure temperature.

Pushbutton switches are mechanical switches defined by the method used to activate the switch.

DC motors are most commonly used in variable speed and torque applications.

Rocker switches are actuated by a standard or dual rocker or paddle

Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit
