Abstract: A switch and speed control assembly for use in a wet/dry utility vacuum or blower is disclosed. The switch and speed control assembly provides a single rotary control actuator for turning the vacuum or blower on and off, for infinitely varying the speed of the motor, and for providing a momentary boost control. The switch and speed control assembly includes a thumb wheel fitted to the shaft of a voltage varying potentiometer, a snap action switch in operable relation to the exterior edge of the thumb wheel, and a compression spring contained beneath the thumb wheel. As the thumb wheel is rotated in an increasing "on" direction, the contacts of the snap action switch are closed, allowing electric current to flow to the motor of the wet/dry utility vacuum or blower. The voltage levels in the motor, and correspondingly the speed of the motor, are controlled by varying the potentiometer voltage through rotation applied to the thumb wheel. During boost operating conditions, the thumb wheel engages the compression spring such that when the force engaging the momentary boost condition abates, the thumb wheel returns to a normal operating condition. Additional features incorporated in the switch and speed control assembly include: mechanical stops for both the "Off" and "High On" modes; a static guard to protect the electrical components and the user from static discharges; fastener free mounting within wet/dry utility vacuum or blower housings; a configuration designed to prevent mechanical loads present on the thumb wheel from being transferred to the potentiometer shaft and other electrical components, such as the switch; and internal wire routing designed to minimize inductive influences between the wires.

Abstract: An electrical implement having a bypass mechanism for controlling a variable speed motor is disclosed. The implement includes a tool, a variable speed electrical motor activatable for driving the tool, a housing supporting the motor and tool, and a control knob for controlling the speed of the motor. The control mechanism includes an on/off switch and a variable speed control circuit. The variable speed control circuit includes a variable resistance rheostat and bypass switch. The control knob controls whether the bypass switch causes current to bypass the rheostat to operate the motor at a predetermined speed or else whether the resistance in the rheostat is variable to change the speed of the motor. The control mechanism includes a cantilevered beam engageable by the control knob to operate the bypass switch. The cantilevered beam is sufficiently flexible to allow for large deflections while placing only limited force across the bypass switch.

Abstract: A speed control mechanism allowing a user to control the operating speed of a power tool. The speed control mechanism includes a drive motor and a handle connected to the power tool including a trigger, a speed governor and a cam assembly. The trigger is displaced from a first position by the user to initiate operation of the drive motor. The trigger cooperates with the speed governor to vary the operating speed of the drive motor based on the displacement of the trigger. The cam control assembly is operated by the user and cooperates with the trigger to control the extent to which the trigger can be displaced from the first position by the user, thereby limiting the operating speed of the motor. In one embodiment, the speed control mechanism is for use with the drive motor of the power tool to control the operating speed of the power tool. In an alternative embodiment, the speed control mechanism is used with a radial arm saw including an anti-kick forward device. In this embodiment, the speed control mechanism controls the operating speed of the motor of the anti-kick forward device, allowing the user to limit the rate at which the saw blade can be moved.

Abstract: A variable speed trigger switch particularly adapted for use with electric power tools such as drills. The trigger switch features clam shell construction and a single vertically disposed circuit board thereby facilitating assembly and resulting in a low cost and compact unit. Wire connections are kept to a minimum through use of the circuit board in accordance with this invention having power contact resistance and wire terminal connectors formed directly on the board. The trigger switch includes a locking feature enabling the trigger switch to be locked at a desired position and further provides an adjustable detent which can be felt by the user during trigger retraction. The electronics package of the trigger switch employs an electronic motor speed control circuit which provides a combination of open loop and closed loop motor control.

Abstract: In a switch, for example, for a device such as a drill, a key switches an ectrical switching bridge at the beginning of the key displacement. A variable resistor is adjusted depending on the travel of the key, thereby controlling device speed. In order to achieve an adjustment of the key end stop, a slide displaceable in the transverse direction is mounted on the key, which slide has a stop edge projecting in the longitudinal direction. A stop border is provided on the switch cover and configured relative to the travel of the slide so that the distance between the stop edge and the stop border varies according to the displaced position of the slide, thereby enabling operator control of the device speed.
