MCQ-1 Proximity switch
Explanation:\u00a0 <\/span>There are several different kinds of proximity switches that can sense the presence of an object without coming into touch with it, including optical, magnetic, and capacitive switches.<\/span><\/p> Explanation:\u00a0 The sensing range of a proximity switch is the distance between the switch and the thing being sensed.<\/span><\/p>","comments":"1","hints":"","question_order":"1","question_type":"0","question_type_new":"0","question_settings":"a:14:{s:8:\"required\";i:1;s:12:\"answerEditor\";s:4:\"text\";s:14:\"question_title\";s:43:\"What
