Abstract
To make a display in a photoelectric switch easy to see for a user. A photoelectric switch includes a housing having a substantially rectangular parallelepiped shape. A display is attached to a first surface of the outer surface of the housing. A control board is housed on the inside of the housing. A controller is mounted on the control board. The first surface includes a hole-like or cutout-like opening section for allowing a signal cable to pass from the outside to the inside of the housing. The signal cable electrically connects the control board disposed on the inside of the housing and the display disposed on the outside of the housing. A cover member includes a window section for exposing a display region of the display and covers a non-display region of the display. The cover member is provided outside the housing.
