A neuromuscular stimulation device is described having a plastic casing housing a printed circuit board bearing control electronics, with the casing including an external integral flexible portion which is capable of being flexed into the interior of the casing so as to cause an electrically insulative substrate on which is carried an electrically conductive pathway to be pushed into contact with the PCB in order to complete an electrical circuit. Such a switch is relatively inexpensive to produce, as it has few moving parts, can be formed in a usual manufacturing process, and is robust.

A signal generator, in particular opening switch, for a vehicle door or flap, including an actuator, in particular an actuator which can be manually actuated and/or gripped by an operating person, furthermore including a plug housing (14) with a switch (22) which is received therein or arranged thereon and which has electrical contacts (20) which form part of a plug connection, and including an actuator housing (12) with the actuator (30), the actuator being mounted movably on the actuator housing (12) and acting on the switch (22), the actuator housing (12) and the plug housing (14) being positionally fixed relative to one another, wherein the electrical contacts (20) are electrically connected to the switch (22) by plugged-in conductors.

An electronic device is provided in the disclosure. An electronic device includes a frame, a stop pin, and a button. The frame defines a button hole and a pin hole in communication with the button hole. An inner side wall of the button hole is provided with a stop protrusion at a position away from the pin hole. The stop pin is inserted into the pin hole and partially received in the button hole. The button is provided with a first hook and a second hook away from the first hook. The first hook hooks the stop protrusion. The second hook hooks part of the stop pin in the button hole. The button can be pressed to slide a preset distance under a limit of the stop pin and the stop protrusion.

A push switch contains a case including a containing portion and a sealing groove; a pair of contacts disposed in the containing portion so as to be spaced apart from each other; a movable contact which is disposed above the pair of contacts in the containing portion; a cap including a base portion disposed on the case and a sealing protrusion protruding from a peripheral edge portion of the base portion toward a lower side for liquid-tightly sealing the sealing groove of the case; and a cover attached to the case from an upper side so as to hold the cap on the case. The sealing protrusion of the cap is compressively deformed in the sealing groove of the case, and thereby the sealing groove of the case is liquid-tightly sealed.

Compliant electrical circuit protection devices are described for use in hazardous environments without presenting ignition risks for potentially explosive environmental conditions. Sensing features and systems may evaluate wiring limits and user selected settings for compatibility, detect loose connections and operating parameters to ensure safe operation of the device, and to intelligently diagnose and manage issues of concern for the circuit protection devices as well as the larger electrical power system.

A seal for securing a cable to a fuse box includes a plastic body and a rubber insert. The plastic body has a receiving cavity along an inner surface. The rubber insert features an outside structure to join with the inner surface of the plastic body, an inside structure to surround the cable, and a fitting rib along an outside surface of the outside structure, the fitting rib to occupy the receiving cavity. The inside structure of the rubber insert moves in response to movement of the cable while the outside structure does not move.

A waterproof button assembly includes a body, an elastic element, a first sealing element, a second sealing element, a lower cover, a circuit board and an upper cover. The body is recessed downward to form an upper accommodating groove. The body is recessed inward to form a lower accommodating groove. A bottom wall of the upper accommodating groove is recessed downward to form a holding groove. The bottom wall of the upper accommodating groove defines a first through hole. The body has an opening. The elastic element is mounted in the holding groove. The first sealing element is mounted around the first through hole. The second sealing element is assembled to the opening. The lower cover covers the lower accommodating groove to form an assembling space. The circuit board is assembled in the assembling space. The upper cover is assembled in the upper accommodating groove.

A tiller for an outboard motor includes a tiller body that is elongated along a longitudinal center axis between a proximal end and a distal end. A throttle grip is on the distal end of the tiller body. A trim switch assembly is located at a distal end of the throttle grip. The trim switch assembly includes a momentary switch and a driver. The driver is configured to output current to activate a trim relay on the outboard motor in response to actuation of the momentary switch.

A switch with an integrated overcurrent protection element can include multiple arc gap between the contacts when opening the circuit during overload protection and switching operations. The switch can include an overcurrent protection element which can make contact with two contact terminals, and which can change to a different shape upon exposure to an overcurrent condition. The overcurrent protection element can also be moved in a direction normal to the two contact terminals between a first position and a second position through the use of a rotary switch to selectively place the overcurrent protection element in contact with the two contact terminals.

An electrical switch (100) includes an insulative housing (110) forming a receiving space therein, a fixed contact set (121, 122) retained in the housing (110), a movable contact set (131, 132) located above the fixed contact set (121, 122), and a cover (140) mounted upon the housing, wherein the moveable contact set (131, 132) further includes at least three outwardly and downwardly extending protrusions (133) on a periphery at equal intervals so as to support up-and-down movement of the moveable contact set (131, 132) during operation with a superior manual feeling.
