Embodiments included herein are directed towards an apparatus for actuating a switch of an operator control device, and related methods. Embodiments of the present disclosure may include a trigger shaped to mate with the operator control device. The trigger may include an integrated preload portion formed, at least in part, within the trigger. The trigger may further include an integrated actuator portion formed, at least in part, at an interfacing portion of the trigger. The integrated actuator portion may be configured to interface with the switch of the operator control device.

A switch, with enhanced operability and capable of changing control circuits independently by one hand, has a printed circuit board, first and second wiring patterns provided on one surface of the printed circuit board, first and second crank members supported for rotation above the printed circuit board, a first switching slider configured to rotate with the first crank member as the first switching slider slides an the first wiring pattern; and a second switching slider configured to rotate with the first crank member as the second switching slider slides on the second wiring pattern. The first and second crank members are positioned at respective positions where they are driven by one hand of an operator.

A power-driven working device including: a working tool; a drive unit configured to drive the working tool; a control unit configured to control an output power of the drive unit; and an operating unit including a first switch and a second switch, is provided. The control unit includes a cruise control unit configured to execute cruise control to maintain the output power of the drive unit constant when a cruise switch is activated, and an output power adjustment unit configured to increase the output power of the drive unit and to continue the cruise control when the first switch is activated during the cruise control, and to decrease the output power of the drive unit and to continue the cruise control when the second switch is activated during the cruise control.

A switch control device includes a casing, a motor, a control unit, and a push arm. The casing includes a mounting wall adapted to be mounted on a mounting surface, and a surrounding wall extending transversely from the mounting wall. The motor is disposed in the casing and has a rotary shaft extending through the surrounding wall. The control unit is connected to the motor. The push arm is disposed outside of the surrounding wall and is coupled to the rotary shaft so as to be driven to rotate relative to the casing without touching the casing, between a pushing state and a release state, thereby controlling the switch.

A switch assembly, a switch assembly starting method and a power tool are provided. The switch assembly includes a housing, a main control switch accommodated in the housing, a locking switch and a trigger switch arranged on the housing. An end of the trigger switch is accommodated in the housing and is in contact with the main control switch. An end of the locking switch is in contact with the trigger switch. The locking switch has a locking position and a releasing position, when the locking switch is in the locking position, the locking switch limits the trigger switch in a locked state, and the main control switch cannot be started; when the locking switch is in the releasing position, the locking switch is positioned beside the trigger switch and limits are removed, the trigger switch is in the release state, and the main control switch can be started.

A redundant and dissimilar system for monitoring the status of contactors of an aircraft control stick. This monitoring system comprises at least one electrical power source, at least one processor and several circuits for monitoring the status of the switches of the contactors. Each monitoring circuit comprises and electrical power source, a switch for each contactor, the switches of a contactor being connected to each other, and an electronic assembly provided with receivers arranged in series with each other. Each switch is arranged in parallel with at least one receiver so as to short-circuit the at least one receiver when the switch is in the closed state. Each processor measures and analyses an electrical feature of the electronic assembly, such as a mains voltage VE as the terminals of the electronics assembly, in order to determine the status of each switch.

The disclosure provides a switch assembly, a switch assembly starting method and a power tool. The switch assembly comprises a housing, a main control switch accommodated in the housing, a locking switch and a trigger switch arranged on the housing. An end of the trigger switch is accommodated in the housing and is in contact with the main control switch. An end of the locking switch is in contact with the trigger switch. The locking switch has a locking position and a releasing position, when the locking switch is in the locking position, the locking switch limits the trigger switch in a locked state, and the main control switch cannot be started; when the locking switch is in the releasing position, the locking switch is positioned beside the trigger switch and limits are removed, the trigger switch is in the release state, and the main control switch can be started.

A preassembled gear shift module is adapted to be connected to a substructure. The preassembled gear shift module includes a cover assembly, a circuit board, and a function button. The circuit board is attached to the cover assembly, and includes a switch. The function button is exposed through the cover assembly, and is operably connected to the switch.

A power-driven working device including: a working tool; a drive unit configured to drive the working tool; a control unit configured to control an output power of the drive unit; and an operating unit including a first switch and a second switch, is provided. The control unit includes a cruise control unit configured to execute cruise control to maintain the output power of the drive unit constant when a cruise switch is activated, and an output power adjustment unit configured to increase the output power of the drive unit and to continue the cruise control when the first switch is activated during the cruise control, and to decrease the output power of the drive unit and to continue the cruise control when the second switch is activated during the cruise control.

A compression brake control shifter for convenient and safe compression brake control from the shifter includes a shifter body. The shifter body is configured to connect to a shift lever of a truck to manipulate a gear system of the truck. The truck has a gear splitter and a compression brake. A wiring harness is coupled to the shifter body and extends through the bottom side to be in operational communication with a CPU of the truck. A compression button, a hi/low gears switch, and a gear splitter switch are coupled to the shifter body and are in operational communication with the wiring harness to activate and alternatively deactivate the compression brake of the truck, to switch to and from a hi gear mode and a low gear mode of the gear system, and to activate and alternatively deactivate the gear splitter of the truck, respectively.
