Abstract: An electrical switch provides a center contact moving between two outer contacts, at least one of which is mounted on a lever. In the event of a contact weld forming between the center contact and the lever mounted contact, unison motion of the lever mounted contact following the center contact during switching causes a strong shear force tending to break the weld. In one embodiment, a fulcrum wall striking the lever of the lever mounted contact causes increased angulation between the contacts so that unison motion rotates and peels the contacts apart.

Abstract: An electric transfer switch includes a three-position toggle mechanism and a crossbar which is mounted on the toggle mechanism. The crossbar carries a plurality of moveable contacts and is rotated by the toggle mechanism. The moveable contacts normally contact one set of the stationary contacts in one closed position which are connected to a normal main power supply. The moveable contacts are rotated to a neutral non-power line in an open position, and are further rotated to another closed position, which are connected to a standby emergency power supply to supply electricity to the transferred electrical loads. The toggle mechanism includes a multi-bar linkage which is rotated by a handle of the toggle mechanism among the open position and two closed positions. A plurality of springs and catches are used to maintain the contact between the moveable contacts and the stationary contacts, even when a "fault" current passes through the contact tips of the moveable and stationary contacts.

Abstract: A tilt responsive switch supported on a hinged structure such as a trunk lid, door or the like includes an oscillating mass or pendulum rotatingly held by a bearing structure located within the switch housing and a pair or electrical terminals electrically connected by a movable contact mechanism. The pendulum effectively controls the motion of the movable contact mechanism. When the electrical terminals are connected by the movable contact mechanism, the pendulum abuts against a first internal switch housing limit bumper. When the pendulum abuts against a second switch housing limit bumper, the movable contact mechanism is disconnected from the electrical terminals.

Abstract: An improved contact mechanism for a switch is disclosed in which impact between contacts is reduced or moderated to minimize rebound of the contacts thereby to prolong the life of the switch. The contacts are sufficiently spaced apart from each other when the switch is in a stable open position, but when the switch is operated, the movable contact is first moved gradually to an intermediate position toward the fixed contact whereafter it is moved rapidly to the fixed contact over a thus reduced distance.
