A multi-pole switch assembly includes a housing, a plurality of switches, and an actuator. The switches are disposed within the housing, and each switch is coupled to receive an actuation force and is configured, upon receipt of the actuation force, to move between a first position and a second position. The actuator is disposed at least partially within the housing and is configured to at least substantially simultaneously engage, and thereby supply the actuation force to, each switch to thereby move all of the switches, with substantial simultaneity, to either the first or the second position. The actuator is rotatable to a plurality of set rotational positions to thereby vary the substantial simultaneity.

An electronic device having a surface-mounted pressable button includes a shell, a pressing piece, a fixing piece, an adjusting piece, and a switch. The shell defines a receiving hole. The pressing piece is movably received in the receiving hole. The fixing piece is fixed in the electronic device and defines a first through hole facing the pressing piece. The adjusting piece is received in the first through hole and is movable along an axis of the first through hole. The switch faces the pressing piece and is fixed to the adjusting piece, and the depth of the switch within the first through hole is adjustable.

A force control module, assembly, or device for controlling a force required to actuate an electromechanical actuator or a set of electromechanical actuators. The electromechanical actuator is for example a computer mouse button, a keypad, or a joystick button. The force control module includes a lever element that is couplable to the electromechanical actuator, and a fulcrum element that is engageable with the lever element at a pivot point or fulcrum point. A displacement of the fulcrum element relative to the lever element varies a position of the fulcrum point. The force required for actuating the electromechanical actuator is at least partially dependent upon the position of the fulcrum point. By displacing the fulcrum element relative to the lever element, and hence varying the position of the fulcrum point, a user can vary the force required for actuating the electromechanical actuator.

A disconnect apparatus for electrical power lines comprises a circuit interrupter having a fixed contact and a moveable contact. A linkage mechanism has first and second coupling elements. The second coupling element is secured to the moveable contact for operating the circuit interrupter. A drive mechanism has an output coupling element. An insulator assemble operatively connects the output coupling element to the linkage mechanism first coupling element. The insulator assembly comprises an insulator having a through bore. An insulator rod extends through the bore and is connected between the output coupling element and the linkage mechanism first coupling element. A dielectric seal is located between the insulator and the insulating rod.
