Portable technological machine // 2631373
FIELD: machine engineering.SUBSTANCE: machine includes a handle housing and a switch with a movably mounted button and an unlocking element for unlocking switch button displacement interlocking device. The switch button is located on the handle section of the handle housing. The unlocking element has a pushable portion located outside the pressed surface of the switch button and is pivotally and/or rotatably mounted around the axis of the unlocking motion, extending in a plane perpendicular to the axis of the switch button motion.EFFECT: convenient control of the technological machine.16 cl, 16 dwg

Technological machine // 2630088
FIELD: machine engineering.SUBSTANCE: processing machine comprises a handle body, a switch having a key installed on the handle body for operating the switching body of the switch, and a support assembly. The support unit is provided in order to communicate the movement from the one end thereof facing the connection area of the handle body to the other end of the hand grip end facing away from mentioned connection region when the switch key is acted upon. The support assembly comprises a linkage mechanism made in the form of a parallelogram mechanism. In this case, the action on the button of the switch causes it to move in the direction of the handle body along the entire longitudinal extent of the pressed surface of the switch key.EFFECT: accuracy of the machine control is increased.16 cl, 8 dwg

Lockable electric switch // 2603839
FIELD: electrical engineering.SUBSTANCE: invention relates to an electric circuit breaker, in particular for electric machine. Electric switch for electric processing machine comprises a first switching device and a second switching device. First switching device is configured for reversible transition from a first switched state to a second state due to movement of a first mechanical signalling element. Second switching device is configured for reversible transition from a third switched state, in which electric switch acts as a pushbutton, to a fourth state, in which electric switch acts as a rocker switch due to movement of second electric or mechanical signalling element. Second switching device comprises a second actuating element interacting with second signalling element. Fourth switching state is allowing fixation of state of electric switch in which first signalling element can be fixed through second actuating element.EFFECT: technical result is providing reliability of controlling process machine.12 cl, 15 dwg

Percussion tool // 2520246
FIELD: process engineering.SUBSTANCE: proposed tool has motor, case, handle damping material, manual working element mode selector, movable element and resilient element. Damping material is arranged between case and handle to connect them so that both can displace relative to each other in axial direction of bit. Manual working element is driven by motor, arranged at said handle and shifted from ON position to OFF position. Mode selector is arranged and tool case to select between first mode whereat said bit is continuously operated and second mode whereat it is driven selectively. Movable element can shift said bit with the help of said mode selector. Resilient element is arranged at vibration transfer path. Said resilient element prevents vibration transfer to handle with mode selector at first ON mode and locks the working element at movable element IN position.EFFECT: damped vibrations at hand-held tool with bit mode selection.13 cl, 16 dwg

Electric device // 2486622
FIELD: electrical engineering.SUBSTANCE: electric device (10) contains packet switch (12) envisaged for power supply switching on and off to a power using unit (14) and control unit (16) in order to control the power using unit (14) that is a motoring unit (80). According to the invention the electric device contains shunting unit (18) provided to supply power to the control unit (16) in case of power supply switching off by the packet switch (12).EFFECT: prevention of undesired run-up time at starting-up or connection of the power using unit.15 cl, 5 dwg

Device to change from clockwise rotation to counter clockwise rotation of electrically driven tool // 2472611
FIELD: process engineering.SUBSTANCE: invention relates to machine building. Proposed device comprises brush part and structural part to be secured on tool vase, and pair of fixed contacts to be connected to motor winding. Said brush part makes motor brush holder to revolve about structural part. Said brush part has pair of moving contacts arranged between fixed contacts to change conditions of contact between said fixed and moving contacts by rotation. End of any said contact represents an elastic end to be deformed in contact with another contact. Structural or brush part has a regulative part adjoining to elastic part for regulation the degree of deformation thereof.EFFECT: longer life.12 cl, 8 dwg

Electric tool with double control switch // 2360318
FIELD: electric engineering.SUBSTANCE: invention relates to electric engineering and may be used as switching unit for electric tools. The switching unit for electric tools contains at least one reset mechanism (29) with switch element (30). The said switch element (30) includes at least two hand-operated control elements for switching on and off the first reset mechanism (29) and clamping element (33) intended for clamping the above mentioned switch element in "on" position. The on-line mode is switched off by the first (36) and second (37) control elements.EFFECT: improved quality of operation and safety.24 cl, 8 dwg

Electric power switch with connecting bus and arcing horn // 2297066
FIELD: electrical engineering.SUBSTANCE: the electric power switch has a body and a connecting bus with an arcing horn with a fastening shelf installed on it. The connecting bus passes through a hole of the rear panel of the body. For connection of the arcing horn to the connecting bus a boss is provided on the fastening shelf of the arcing horn, and a recess receiving the boss-on the connecting bus. The fasteners catch a jumper located on the lower side of the connecting bus. At pushing in of the connecting bus with the laid over arcing horn, its fastening shelf from above and from the side is overlapped by a bead positioned on the body. Thus, the fastening board becomes free of the fasteners.EFFECT: simplified wiring of the connecting bus and arcing horn and improved accessibility of the fastener for the arcing horn.4 cl, 2 dwg
