    摘要： A safety switch assembly having a handle pivotably attached to a casing to allow selective operation of an electrical contact assembly. The handle is attached to the casing with a movable pivot such that excessive grip pressure renders the safety switch inoperable until the safety switch is reset. The handle is moveable responsive to grip pressures that range from no actuation to a first grip pressure. Actuation of the handle in this range controls operation of the electrical contact assembly. Gripping of the switch with a grip pressure greater than the first grip pressure moves the pivot such that the safety switch is rendered inoperable, or non-conductive, until manipulation of a reset actuator returns the pivot to a pivot position associated with the first operating zone. Such a construction provides a safety switch that can be rendered inoperable and reset to allow subsequent operation.

    摘要： The invention relates to a safety switch intended to be connected into a safety circuit for an industrial machine, for example an industrial robot. The switch comprises a contact device (2) with a hand-operated device (3, 4) in which a pressure rod (31) is displaceable against the action of a return spring (33) from a first end position via an operating position to a second end position, the safety circuit being closed only in the operating position. During the return movement of the pressure rod from its second to its first end position, the contact device (2) is not affected, and the safety circuit thus remains open during the whole of this return movement.

    摘要： A control switch proximate a support handle of a power driven machine provides for emergency deenergization of the machine without releasing the operator's grip on the support handle. The apparatus of this invention includes a control member (60) which moves from an at rest position along a selected direction (78) and against a first biasing force (70), (36) by motion of the operator's finger and further to an emergency off position by further motion of the operator's finger. A first biasing force (36), (70) continually urges the control member (60) to the at rest position. An activating means such as sliding contact switch (54), (56) and (66) is responsive to movement of the control member (60), and is connected to the driving source of the machine such that the driving source is in a nonoperating condition when the control member is in the at rest position and is in operating condition when the control member is moved to the energizing position. A second biasing force (84), (40) is provided which is stronger or in addition to and requires more force than the first biasing force to resist further motion. A deactivating means such as a normally closed emergency off switch (58) is responsive to further movement of the control member (60) to the emergency off position and will deenergize the machine such that a panic tightening of the operator's grip results in the machine being brought to a stop.

    摘要： The invention relates to a safety switch unit (1) for electrically controlled machines for use in combination with the actual control elements of the machine control system in a hand-held application or for manual control, with at least one operating element which is displaced relative to a mounting frame (8) in accordance with the switching function desired by a user, which is designed to change the switch status of at least one electric switch element, the safety switch unit (1) having at least one switch position which is maintained only as long as a sufficiently high operating force is applied to the displaceable operating elements. Two operating elements for at least one respective electric switch element (14, 15) can be displaced in translation or rotation to a limited degree relative to the mounting frame (8) about a respective pivot axis of two pivot bearings and provide a substantially translating or straight operating movement of the safety switch unit (1) by means of a push button unit (2) which is disposed in front of the two operating elements by reference to the operating direction—arrow (13)—of the safety switch unit (1).

    摘要： There are provided, together with two microswitches 20 accommodated in a cylindrical compartment 13, a manipulation member 2 which can freely swing about a pivot portion 2a in the directions of arrows A and B, a transmission member 3 which can freely move in reciprocating motion within a specific range between a transmitting position and a non-transmitting position located along a radial direction of an arc which is the trajectory of the swing motion of the manipulation member 2 in the directions of the arrows A and B, a contact member 4 which can freely move in reciprocating motion within a specific range between an exposed position and a retracted position in the directions of arrows E and F, a driven member 5 which can freely move in reciprocating motion in the directions of arrows G and H, and a restricting part 6 fixed at a position opposing the contact member 4. The swing motion of the manipulation member 2 in the direction of the arrow B up to a point where the manipulation member 2 goes into contact with the restricting part 6 is transmitted to the microswitches 20 via the transmission member 3 and the driven member 5, and the swing motion of the manipulation member 2 in the direction of the arrow B is not transmitted to the microswitches 20 after the contact member 4 has gone into contact with the restricting part 6. This arrangement makes it possible to achieve improved operability of an enable switch, enhanced safety with the provision of multiple contact mechanisms, and easier installation of the enable switch on a portable operator panel.

    摘要： The invention relates to a safety switching device (1) for electrically controlled machines, for use in combination with the control elements of the machine control-system itself during manual operation, in which the multi-action safety switching device (1) has several channels or several switching circuits (7, 8) and the switching circuits have at least one operating element (2, 3) which can be adjusted by an operator depending on the desired switching function. Each switching circuit (7, 8) has at least one position-sensing device (14, 15), comprising in particular contactless detection devices (16, 17) for detecting, at any time, the position (4 to 6) of the operating elements (2, 3) corresponding to the respective switching stages, which can be adjusted by the operator.
