摘要： A low keylock unit includes an electrical switch unit. A pair of laterally spaced locking levers are pivotally mounted within a rotatable lock tube. The tube extends inwardly into a contact carrier rotatably mounted at the inner end of the switch housing for selective rotation thereof. A rotating switch is coupled to the carrier and selectively engages a fixed contact on a back plate closing the housing. Each lever includes a control leg between a key opening and the pivot and a lock leg between the pivot and the switch unit. A resilient element such as a coil spring compressed between the lock legs or an integral cross between the levers, bears the levers with the lock legs engaging locking grooves on the housing wall to prevent rotation of the tube and the switch unit. A flat key inserted into the lock deflects the legs and pivots the levers outwardly to release the lock legs. If the key is too wide, the control legs move outwardly into the grooves and maintain the locked state. An appropriate key has a final position which partially deflects the control legs within the tube and deflects the lock legs within the tube and thereby positions all legs in a release position within the tube. The control legs and the key are shown with mating truncated edge projections on the control legs and recesses on the key to set the release position and resiliently holds the key within the lock.
摘要翻译：低键锁定单元包括电开关单元。一对侧向间隔开的锁定杆枢转地安装在可旋转锁定管内。管子向内延伸到可旋转地安装在开关壳体的内端的接触载体中，用于其选择性旋转。旋转开关联接到载体并且选择性地接合封闭壳体的背板上的固定触点。每个杠杆包括在键开口和枢轴之间的控制腿和枢轴与开关单元之间的锁定腿。弹性元件例如在锁定腿之间压缩的螺旋弹簧或杠杆之间的整体十字架，其中锁定杆与锁定杆接合在壳体壁上的锁定槽以防止管和开关单元的旋转。插入锁中的扁平键使腿部偏转并向外枢转杆以释放锁定腿。如果钥匙太宽，控制杆向外移动到槽中并保持锁定状态。合适的键具有使管内的控制腿部分偏转并使锁定腿在管内偏转并由此将所有腿定位在管内释放位置的最终位置。控制腿和键被显示为在控制腿上的配合的截头边缘突起和键上的凹槽以设置释放位置并弹性地将钥匙保持在锁中。

摘要： A solenoid starter switch unit for garden tractors, outboard motors and the like operating in a vibrational environmental has an insulating housing with a coil chamber and an outwardly extending rectangular contact chamber. A coil unit supported in the coil chamber has a magnetic plunger with a contact pin journalled in one end and projecting into the contact chamber. The pin has an intermediate contact ledge and a contact has a flat base abutting the contact ledge. The contact is a winged-shaped strip of constant width substantially corresponding to the ledge and is symmetrically formed with a flat base on an inclined portion connected to an outer flat contact portion parallel to the base. An outer lip projects laterally and inwardly from the contact portion. A clamp nut on the pin has an outer edge engaging an outer portion of the base. Coil leads in one embodiment project through the top housing wall. Terminals are press fitted within receptacles on the top of the bobbin. The coil leads pass through top openings in the bottom and are wound about the terminals and soldered in place. The coil leads in another embodiment extend from the bottom of the bobbin and laterally through recessed guides to a bottom terminal chamber. A bottom coil clamp has a projection between the guides to hold the bottom against rotation and clamp the coil within the housing.

摘要： A keylock switch has a standard housing and rotary switch unit for two, three, four, five or six terminals. The switch includes an outer housing has a lock section and an inner contact section closed by a back plate with fixed contacts secured thereto. A keylock assembly includes a rotating tube with edge slots and pivoted locking levers which are pivoted to a release position within the tube. A hub extends from the lock section into a contact chamber and forms a bearing wall, on which a contact carrier plate bears. A rotating U-shaped contact is coupled to the plate bottom and includes an integral leaf spring in the center acting between the carrier and a fixed terminal plate. The U-shaped contact includes opposite end contact plates, with one about twice the width of the other to span two adjacent fixed contacts while the shorter plate engages a single fixed contact. A coil spring encircles the hub, with end ears bearing on spaced ends of a circumferentially extended housing tab to stress the coil carrier spring. A spring tab is located between the ears engages an ear to further stress the coil spring after a selected angle and create a reset force. A stop tab on the carrier and housing limit rotation of the carrier. Fixed contact locations are located on the back plate.

摘要： A solenoid unit for use in high amperage environments includes a hollow cup-shaped housing having a closed end and an open end. A contact section is located adjacent to the closed end, and a coil section is located adjacent to the open end. The closed end includes an end wall. First and second power contact terminals each include a threaded member extending exteriorly for receiving a lead clamping nut. Each terminal includes an enlarged mounting head embedded within the end wall, with an inner contact extending from the end wall. Each head includes a circumferential knurled surface to oppose rotational and axial forces and thereby permits high clamping torque forces on the nut. A bridging contact is aligned with the inner contact ends of the terminals and moves axially thereof. The housing includes inwardly extending opposed locating members which define the contact chamber and guide the bridging contact within a free space to cool the contact assembly. The coil assembly is coupled to position the contact between engagement with the contact ends and spaced therefrom.
