Abstract:
There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes articulated driver means coupled to be driven by the rocker paddle when it is depressed and to urge the rocker paddle back to its out position. When the rocker paddle is pushed in, it urges the articulated driver means to rotate a cam means in a first, clock wise direction, or a second, counter clockwise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and to determine its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by the articulated drive means to pivot back to its initial position. The rocker paddle of the switch is not located within a frame and has surface along its vertical axis of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distance from a datum plane. This surface has zero second differential when the rate of height increase of individual splines is constant.
Abstract:
The present invention is related to a manually operated switch device for the control of electrical equipment. The electrical elements of the switch are assembled in a housing (28) and the mechanical elements are mounted on a body piece (15) attached to the housing (28). The invention is based on adapting at least one linearly transferrable slide member (14) to the said body piece (15), said slide member having contact or guide surfaces adapted to cooperate with the stationary contacts (26). To the slide member (14) is connected via at least one spring-type element (10) a power-spring-arming plate (11), which is movable parallel with slide member, in such a manner that during the movement of said power-spring-arming plate (11), the slide member (14) is moved correspondingly under the force exerted by power springs (10). By virtue of this arrangement, the switching phase occurs always in a consistent manner irrespective of the speed used for rotating the switch operating lever (1).
Abstract:
A multiple switch has a switching actuator manually or automatically movable and a predetermined number of switching contacts controlled by corresponding movements of the actuator. On a base plate are directly mounted adjacent to each other a predetermined number of in themselves already known sealed single-pole touch control make-break switches (10a-10d) in such a way that a revolving actuator (26) with control cams (28), at least indirectly rotatively held by the support plate, when rotated to predetermined posititions actuates touch controls of the touch control switch mounted on the conductor board (20). The support plate can be a conductor board and bear as a stationary part an intermediate bearing part (24) for the revolving actuator. This intermediate bearing forms single piece pressure transmitting means (31) mounted between the touch controls of the touch control switch and the control cams of the revolving actuator to absorb forces acting laterally upon the touch controls.
Abstract:
There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch "on" or "off'. The lower edge of the paddle pivots in and out about its upper edge. The switch includes flexible driver means coupled to be driven by the rocker paddle. When the rocker paddle is pushed in, it urges the flexible driver means to rotate a cam means in a first, clock wise direction, or a second, counter clock wise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and determines its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position. The rocker paddle of the switch is not located within a frame and has a surface along its vertical axis of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distances from a datum plane. This surface has zero second differential when the rate of height increase of individual splines is constant.
Abstract:
There is disclosed a robust on-off rocker paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch "on" or "off'. The lower edge of the rocker paddle pivots in and out about its top or upper edge. Bias means urges the lower portion of the rocker paddle to always be in its out position whether the switch is in the "on" state or position or the "off "state or position. The rocker paddle of the switch is not located within a frame and the surface of the switch has, along its vertical axis, a contour of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distances from a datum plane. The contour has zero second differential when the rate of height increase of individual splines is constant. An actuator coupled to the rocker paddle (the face) of the switch causes a cam to rotate in a clockwise direction and in a counter clockwise direction as the rocker paddle is alternately depressed. The rocker paddle pivots about its top edge and repeated pressing on the lower surface of the rocker paddle causes the actuator to alternately rotate the cam in a clockwise direction and in a counter-clockwise direction. Alternate rotation of the cam drives a slider member having a triangular shaped cam follower along a first and a second opposite direction along a common linear axis. A cam shaped leaf spring cooperates with the triangular shaped cam follower to aid in the movement of the slider and determines its at rest position. An indicator such as a light can be used to indicate the state of conduction of the switch.
Abstract:
The invention relates to an electric switch (1) for electric hand tools such as drills, right-angle grinders, circular saws, surface milling cutters, hedge clippers, or similar. Said switch comprises at least one contact system (3) with a switching contact (4) that can be displaced to switch between an open and a closed position and a fixed contact (5) that interacts with the switching contact (4) in the closed position. The switch (1) has an actuating organ (6) which acts upon the switching contact (4) to effect the switching operation. Delay means (8) which co-operate with the switching contact (4) are provided in the switch (1) to delay the switch from being displaced into at least one of the two switching positions, in particular into the closed position. The delay means (8) and the actuating organ (6) are located on the same side of the contact system (3). Alternatively or in addition, the co-operation between the delay means (8) and the switching contact (4) during the displacement of the switching contact (4) into the other switching position, in particular into the open position, is reduced to such a degree, that the switching contact (4) is essentially displaced into the other switching position without delay.
