Abstract: The invention relates to a handle with an integrated switch (20) for doors or hinged flaps of vehicles. The push-button switch is essentially made up of two components which can be fitted together. The first component (21) is made of a single-pieced injection-moulding product made of three plastic components which comprise a solid covering-shaped housing and an elastic membrane. Said membrane closes the housing cover (22) at the base on one end thereof, thus giving the component (21) a shell shape. A solid pressure activator (24) on the membrane (23) is used as the third plastic component. The second component (31) is formed from a circuit board (33) comprising connected cables (19) and a microswitch (30) mounted thereon. The second component (31) is inserted into the inside of a shell (26) of the first component (21). The circuit board (33) is oriented towards the shell opening (28) and is projected from the edge of the shell (43) of the shell-shaped component (21).

Abstract: A indexing wheel mounted in the head assembly of a safety switch has an axis of rotation extending at right angles to the longitudinal axis of the plunger, and against whose lateral surface the plunger bears. A key channel in the head assembly is adapted for receiving a key and into which the indexing wheel projects. A key, upon being inserted into and upon being withdrawn from the key channel positively rotates a cam plate about its axis of rotation and switches over the switch. The switch and key is maintained in locked status by action of the locking hole on the cam pin and by action of the plunger when a key is inserted into the head assembly where the plunger becomes inserted in the locking hole of the indexing wheel and/or the flank on the cam pin after rotation by the key causing the key and switch to become locked.

Abstract: A key operation detection unit of an electronic keyboard instrument that suppresses increase in reaction forces with key depression operation, to improve a key touch feeling. A depression operation of any one of keys of the keyboard instrument is detected by first and second corresponding detectors of the detection unit. The detectors are surrounded by an outer resilient projection and each comprised of an inner resilient projection and a movable portion extending therefrom toward a base plate of the unit. With key depression, the movable portion of the first detector is in contact with the base plate and its inner resilient projection is deformed to generate a reaction force. With further key depression, the inner resilient projection of the second detector brought in contact with the base plate is deformed to generate a reaction force smaller than the reaction force from the first detector.

Abstract: A mechanical power breaker for a vehicle has a casing, a power input, a master power output, and a breaker positioned in the casing and electrically connected between the power input and master power output. The breaker has a seat, a conductive connector, a moving element, and a first and second resilient supports. The conductive connector is held in seat by the first resilient support and formed by multiple conductive blocks stacked together. The conductive connector and first resilient support are electrically connected between the power input and the master power output. The hollow moving element is held in the seat by the second resilient supports to surround the conductive connector. If the casing is shaken, the moving element is moved to hit the conductive connector. The conductive connector is separated into the multiple conductive blocks to disconnect the electronic connection between the power input and master power output.

Abstract: A switch assembly for an electrical panel configured to receive electrical power from either a first power supply or a second power supply. The switch assembly includes a transfer switch operable to electrically connect the panel to receive electrical power from the second power supply when power is interrupted from first power supply. An indicator light at the panel illuminates so as indicate that electrical power from the first electrical power supply is restored while the transfer switch is positioned to receive electrical power from the second electrical power supply. A light switch is connected to selectively interrupt illumination of the indicator light. An interlock member interconnects the light switch and the transfer switch so that movement of the interlock member to connect the electrical panel to receive electrical power from the first power supply simultaneously moves the light switch so as to interrupt illumination of the indicator light.

Abstract: A crossbar assist mechanism is for a circuit breaker including a housing, a movable contact, a stationary contact, and an operating mechanism. The operating mechanism includes a crossbar, a carrier coupled to the crossbar, and a movable contact arm which is pivotably cooperable with the carrier. The movable contact is disposed on the movable contact arm. The crossbar moves the carrier and the movable contact arm, thereby moving the movable contact into and out of electrical contact with the stationary contact. The crossbar assist mechanism includes an electrically conductive member electrically interconnecting the carrier and the movable contact arm to a load terminal. A spring disposed between the crossbar and the electrically conductive member biases the crossbar from a first position corresponding to the movable contact and the stationary contact being separated, toward a second position corresponding to the movable contact being in electrical contact with the stationary contact.

Abstract: A line switch able to modulate light includes an upper cover, a lower cover and a rotary selector positioned between the upper and the lower cover. When the rotary selector is turned clockwise, the line switch can turn on and modulate light to be half bright, and when the rotary selector is further continuously turned clockwise, light can be modulated to be fully bright, but when the rotary selector is further turned clockwise again to return to the original position, the line switch will be under an OFF condition again. Thus the line switch has two stages of different lighting in addition to the function of turning on and off.
