A switch actuating mechanism having lost motion means

A switch 2 actuating mechanism, eg for an electrically-powered lawnmower, comprises lost motion means 9 which may be either in the form of a leaf spring, made of steel or polymer (eg acetal polymer), or a coil spring. The spring 9 takes up movement of actuating member 8 when member 8 is pressed by lever 3a and safety interlock button 7 is not operated, which retains release slide 6, of the switch 2, in its non-operating position. The lawnmower is started by first pressing lever 3, against handle H, and then depressing button 7, or vice versa, so as to release the slide 6 which is biassed into its operating position by the spring 9 (see fig 3). Damage to lever 3 is minimised since only the load of the spring 9 is transferred to the lever 3 If an operator attempts to start the lawnmower without depressing button 6. In addition slight relaxation of grip by the operator will not cause the switch 2 to turn off as the mechanism provides adequate over-travel.

PIVOTING HANDLE AND CONTROL ARRANGEMENT FOR A FLOOR CARE APPLIANCE

The invention is a pivoting handle and control arrangement for a floor care appliance such as a vacuum cleaner. An actuator rod in the handle is utilized for remotely triggering a switch located in the lower part of the housing. The switch could be utilized for controlling a feature of the floor care appliance such as a surge control for a vacuum cleaner's suction motor. A trigger positioned on the handle is operatively connected to an actuator rod traversing the interior of the handle. The distal end of the actuator rod is in operative engagement with the switch when the handle is in the upright position. When the trigger is depressed, the actuator rod depresses the switch causing it to close. The feature controlled is thereby energized. When the handle is moved to the folded position, the actuator rod is folded with the handle and moved away from the switch.

Cordless, battery operated surical tool

A powered surgical tool includes a motor, a motor control module for controlling the actuation of the motor, and a trigger assembly for allowing the user to enter user-selected commands indicative of desired motor rotation. The trigger assembly includes a number of moving magnets located adjacent the sealed housing that contains the circuitry forming the motor control module. There are a set of magnetic field sensors in the motor control module housing. As the magnets are displaced in response to the user's actuation of the switches, the sensors generate signals representative of the user-selected motor commands. The motor control module further includes a motor control circuit and a direction controller circuit that allow the motor to be driven in either forward, reverse or oscillatory rotation. When the motor is driven the oscillatory rotation, the direction control circuit and the motor control circuit cooperate to ensure the periodic reversal of the motor does not generate significant mechanical vibrations.

Force switch

A mechanical force switch to be disposed along a longitudinal device axis of a medical device includes an electrically conductive switching piston to form a first electrical contact of the switch, a hollow body, an end stop, a bias device, and an electrically conductive second contact of the switch electrically insulated from the piston. The piston is movably disposed in the body hollow along the axis to define different switch-making and -breaking positions. The piston is also movably disposed in a cavity of the stop and the stop is disposed in the body. The stop can be a smooth or threaded puck. The bias device surrounds the piston and imparts bias against it to retain it in one of the two positions until an external axis force overcomes the bias, at which time the switch indicates a state changeover. The switch can be normally open or closed.

Switch for lighting a gas flame

Magnetic key operated switch for electrically operated hand tools

This invention relates to a switch for electrically operated hand tools, and the like, wherein the contact points of the switch are normally maintained yieldably separated, and one arm of said points is movable, and a ring is provided for the user of the device having a magnetized key, shaped to fit the particular key opening of the tool, so that when the key, mounted on a ring worn on a finger of the user, is inserted into the key opening, the movable arm will be moved into closed position, completing an electrical circuit through the motor of the tool, and upon removal of the key, for any reason, the tool will be immediately deactivated.

Switch mechanism

A manual tool is driven by an electric motor, and has a primary handle and a secondary handle arranged at a distance from each other. A switch is situated in the manual tool and can only be switched on by the simultaneous actuation of two contact mechanisms, one arranged in each handle, the motor being switched off when grip on either handle is released. The tool further comprises an initiating device in the form of a safety interlock mechanism which is adapted to prevent actuation of the switch, unless the safety interlock mechanism is actuated prior to actuation of the contact mechanism arranged in the primary handle. The switching mechanism is particularly suitable for a hedge clipper or chainsaw, especially a cordless tool.

Trigger speed control switch

A speed control subassembly is made by providing a generally flat heat sink plate having a laterally-formed collector strip at its upper edge. A double-sided-adhesive insulator tape strip is stuck to the heat sink, this tape having a hole large enough to receive a thyristor chip so that the thyristor anode contacts the heat sink with solder paste therebetween. Two formed terminal strips extending in opposite directions are stuck to the tape so that one contacts the cathode and the other contacts the gate of the thyristor chip with solder paste therebetween. A chip capacitor is placed across the terminal strips with solder paste therebetween. A small force is applied to the capacitor and then heat is applied to the stack of parts to solder the parts together and to the heat sink and to set the adhesive resin. This subassembly is then placed into a trigger switch housing and connected to the contacts and variable resistor thereof to provide a trigger speed control switch for portable tools.
