PURPOSE: To obtain a switch with excellent operability and offering ease of setting operation by providing an output means producing stepwise an output in proportion to the degree of depression of a switch button so as to set a prescribed object value simply.
CONSTITUTION: In interlocking with the depression of the switch button 12, a moving contact main body 13 is moved downward, a 1st moving contact 18 pressed into contact at first is in contact with a 1st fixed contact 21 at the lower position and conducted, and in depressing further the switch button 12, a 2nd moving contact 19 is in contact with a 2nd fixed contact 22, and a 3rd moving contact 20 is in contact with a 3rd fixed contact 23 similarly, and the stepwise output proportional to the degree of depression is obtained by one depression. Since the degree of depression of the switch button is adjusted for the contact strength, the output value to be approached proportionally thereto is operated while being properly subject to speed change stepwise and the object value is set easily.
