摘要： A limit switch operating head includes a shaft rotatable in clockwise and counter-clockwise directions, a cam member supported on the shaft and that is rotatable in the clockwise and counter-clockwise directions responsive to rotation of the shaft, and a follower actuated by the cam member responsive to rotation thereof, with the follower including a pivot pin, a lever portion pivotable about the pivot pin, and a rolling pin mounted to the lever portion and in contact with the cam member. An actuator member contacts the lever portion and translates linearly in a first direction or second direction responsive to pivoting thereof. The rolling pin moves along a profile of the cam member upon rotation of the cam member so as to cause the lever portion to pivot, with the actuator member linearly translating in the first direction or the second direction responsive to the pivoting of the lever portion.

摘要： A rotational over travel protection device for preventing over rotation of at least one of a cable, or a component operable with the rotational over travel protection device is provided. The device includes a housing, a rotatable shaft connected to the housing that can rotate relative to the house, and a triggering device supported in the housing and rotatable with the rotatable shaft. The device also includes a first and second rotational limit switch disposed in the housing. The switches are operable to be activated by the triggering device to arrest rotation of the rotatable shaft upon relative rotation of the rotatable shaft and the housing either a first or second rotation direction, respectively, at least 180 degrees from a zero position.

摘要： A limit switch may be provided with a switch body having a contact mechanism inside, and an operation unit connected to the switch body. The operation unit comprises an elastic part that energizes the operation lever from the first motion position towards the return position via the pivoting shaft and the first cam, and energizes the operation lever from the second motion position toward the return position via the pivoting shaft and the second cam, a first cam's pivoting restriction part that restricts the pivoting of the first cam in a first direction in which the operation lever moves from the return position to the second motion position, and a second cam's pivoting restriction part that restricts the pivoting to the second cam in a second direction in which die operation lever moves from the return position to the first motion position.

摘要： A limit switch is provided with a switch body having a contract mechanism inside, and an operation unit connected to the switch body. The operation unit may include a pivoting shaft support that permits pivoting of the pivoting shaft with respect to the housing body in a state of an external force along the extending direction of the pivoting shaft being not applied to the operation lever, and contacts the peripheral wall to support the pivoting shaft in a state of an external force along the extending direction of the pivoting shaft being applied to the operation lever.

摘要： A spring piece is formed integrally as part of a drive arm that presses an operational body. The spring piece is disposed between a pressing part at which the drive arm presses the operational body and a linkage part that acts a swinging fulcrum. A contact part between the spring piece and a case is positioned closer to the linkage part than the bend bottom end is. When the drive arm swings from an initial orientation to a completely swung orientation, the spring piece can generate an elastic return force. The elastic return force does not largely increase even when the drive arm swings.

摘要： An electrical product includes a housing with a movable cover and at least one module receiving slot that can be closed by the cover. The housing carries control circuits. A proximity switch is carried on the module. When the module is inserted into the slot and the cover is closed, an electrical signal can be coupled to the control circuits in the product. When the cover is opened, a different signal can be coupled to the control circuits in the product. A first latch element can be carried on the housing, adjacent to the slot, to retain the cover in the closed state. A second latch element releasibly engages the first latch element when the cover is closed.
