<p>PROBLEM TO BE SOLVED: To provide a detection switch by which a set threshold level or a detected quantity is accurately recognized. SOLUTION: A photoelectric switch master set 100 is provided with a processing section 1 and a control section 2. An LCD section 23 is connected to the control section 2. A sensitivity switch 18 is operated to set a threshold level automatically by a sensitivity setting control section 6 of the processing section 1. A display channel of the LCD section 23 is selected by operating a mode switch 21 and an UP switch 19 or a DOWN switch 20 and a display mode is revised by operating the mode switch 21. Light receiving amount data, threshold level data or relative data for the set channel are displayed on the LCD section 23. A threshold level set by the sensitivity setting control section 6 is fine-adjusted by operating the UP switch 19 or the DOWN switch 20.</p> |
