Notes:
• 3-position switches operate with direct opening action
• For the output of the enabling device, use terminals 1-2 and 3-4.
• The above operation characteristics show when the center of the button is pressed. Pressing the edge of a button turns on one contact
earlier than the other contact, causing a delay in operation.
