Abstract
1,154,003. Retractive switches. E. MARQUARDT, J. MARQUARDT, H. MARQUARDT and E. MARQUARDT [trading as J. & J. MARQUARDT]. 19 Sept., 1966 [23 Sept., 1965], No. 41737/66. Heading H1N. A microswitch has a contact arm n articulated to a lever k by a toggle link r. The lever k is pivoted at v to a terminal bracket member i having an aperture through which the contact arm n extends. When the switch is operated by depression of button l the aperture limits the movement of the contact arm so that the effective axis of the toggle link r does not pass the pivot point v and hence the tension spring m exerts a restoring couple on lever k making the switch inherently retractive. The pivotal movement of lever k provides some longitudinal sliding movement of arm n which serves to break any welding of the contacts.
