Abstract: A switch (10) for controlling flow of electric current includes a base (12) and a carrier (100) supported for movement on the base. An engagement surface (60, 80) disposed on the base (12) includes a ramp surface (66, 86) and a detent surface (64, 84) defining an opening (62, 82) disposed adjacent to the ramp surface. A detent member (130, 132) on the carrier (100) is engageable with the detent surface (64, 84) when in the detent opening (62, 82) and is engageable with the ramp surface (64, 84) when not in the detent opening. The switch (10) has a start condition in which the detent member (130, 132) is disposed in the detent opening (62, 82) and resists movement of the carrier (100) relative to the base (12). The switch (10) is movable under an actuation force from the start condition to an actuated condition in which the detent member (130, 132) is disposed on the ramp surface (66, 86). The switch (10) returns to the start condition in response to the release of the actuation force.

Abstract: A switch mechanism for electrical service quick connect/disconnect, especially suitable for electric vehicles. The switch mechanism includes a handle for turning a shaft which, through a lost motion connection, rotates a gear in engagement with a rack. The rack moves the switch contacts from a disconnect to a connect position to make and break electrical connection between the vehicle battery pack and the vehicle electrical system. An over center device biases the handle into either a full connect or a full disconnect position once the handle passes an intermediate position. A spring forces a locking detent into a notch on the rack to prevent inadvertent movement of the rack from the connect position, and a cam mounted on the shaft actuates a cam follower portion of the locking detent to move the locking detent out of the notch and allow the rack to move to its disconnect position. Further springs are compressed in response to movement of the contacts to their connect position.

Abstract: A control device for an electrical switch is suggested, which is composed, among other things, of an actuation element (1) as well as at least one latching pin (3) that is under the effect of a compression spring (2) and a system having at least one latching track (4) interacting with the latching pin (3). In the latching track (4), at least one molded pathway (7) lying inclined to the actuation directions is present, which upon a displacement of the latching pin (3) in one of the actuation directions necessarily produces a simultaneous displacement of the latching pin (3) in the other actuation direction. The control device designed in such a way serves the purpose of realizing the functions of both angular and axial displacement and in addition, of insuring that the electrical switch can only be brought into permissible switching positions by movement of the actuation element (1).
