Abstract: A keyswitch structure with a keycap having a balance lever is disclosed. A balance lever is pivotally installed within a keycap of a key switch. The balance lever is formed with two hooks. The balance lever is slidably matched to slots in a key seat. At least one block element (having a shape like a rib) is installed within the keycap. As the balance lever is not installed in the slots, the block element will generate a force to support and stop the balance lever so that the keycap of the key seat can not be assembled in the key seat normally and thus, it is failed in testing. Therefore, bad products can be found in the testing process. In the present invention, since a dull-proof structure is added to the balance lever of a key switch, it will prevent from unbalance due to the ineffectiveness of the balance lever as that in the prior art.

Abstract: Disconnector contact drive devices for switchgear for power supply and distribution are described, in particular for air-insulated medium-voltage switchgear, having movable pole units. In where in a first movement sequence, the disconnector contacts are separated from fixed mating contacts of the switchgear. In a second movement sequence, the pole units are displaceable to achieve the isolating distance, and the disconnect contacts are moved to disconnect them by force components acting in the x/y directions. The disconnector contact drive devices are equipped with linear guide shafts. The pole units contain pole box frames which are linearly movable along the guide shafts from an ON position stop to an OFF position stop due to the forces acting on the toggles. The toggles each have four pivot bearings.

Abstract: A flow switch for a high pressure washing system or other flow-related system is disclosed. The flow switch switches from an open to a closed position in the presence of adequate flow in a water or other fluid-carrying pipe. The flow switch includes a cartridge body, a sensor, a plunger, a magnet, and a spring. The cartridge body has an inlet port and an outlet port which allows fluid to flow into the cartridge body, through a flow chamber, and out of the cartridge body. The cartridge body also has a sensor chamber for accommodating the sensor. The sensor is positioned within the sensor chamber and is used to determine whether fluid is flowing through the flow chamber. A plunger is positioned within the flow chamber, and is responsive to fluid flow. Between the plunger and the sensor is a spring. The spring prevents the plunger from coming in close proximity to the sensor absent fluid flow.

Abstract: A canceling ratchet consists of ratchet body portion 31, ratchet movable portion 32 enabled to move in a forward and backward direction in ratchet body portion 31, and a movable portion pushing spring 40 provided between these portions. When a grabby brake phenomenon occurs in turn lever 24, ratchet movable portion 32 moves in direction of arrow G1 against a spring force of movable portion pushing spring 40. When a cancel operation is performed, the direction of vector F1 differs by nearly 90 degrees from the direction of movement of ratchet movable portion 32, and from the direction of expansion and contraction of movable portion pushing spring 40. Thus, the magnitude of a vector F4 representing a force acting on movable portion spring 40 is relatively small, exerting a small influence on the movable portion pushing spring.
