  • Patent number: 8981244
    Abstract: The present invention relates to a forward/backward rotation switching mechanism, comprising: a cover, a turntable, a terminal-fixing body, a first contact terminal, and a second contact terminal. In the present invention, a plurality of dust-off trenches are especially formed on the peripheral edges of the turntable for preventing from the dust accumulation between the turntable and a cover; therefore, even if the forward/backward rotation switching mechanism is used in an environment having a lot of dust, the turntable can still be turned around because the dust is ruled out by the dust-off trenches.

  • Patent number: 8076603
    Abstract: An axially-movable rotary switch includes a casing, a fixing base, a substrate and a knob. The fixing base is fixed in the hollow casing. The substrate is fixed below the fixing base. The knob is pivotally disposed on the upper end of the hollow casing. The switching rod of the knob eccentrically penetrates a positioning hole of the fixing base. The elastic piece is disposed at the distal end of the switching rod and is brought into contact with the electrical contacts of the substrate. With the elastic piece of the switching rod being arranged to correspond to the electrical contacts of the substrate, a user can switch the states between a closed circuit and an open circuit by axially drawing/pressing the knob. Further, the contact between the elastic piece and the electrical contacts will not generate unnecessary frictional interference, so that the lifetime of the device can be extended.

  • Patent number: 7291796
    Abstract: A press switch includes a base, a contractible pulling rod, an upper casing, and an actuator, and when the actuator is pressed to compress a resilient spring between the upper casing and the actuator, such that the contractible pulling rod and its press terminal move downward until two movable contact points are in contact with two fixed contact points of input/output terminal on both sides of the base to electrically connect to power supply If the actuator is released, the extension of the resilient spring lifts the contractible pulling rod and its press terminal, and thus the two movable contact points are forced to be detached from the fixed contact points of the input/output terminals on both sides, so as to disconnect the power supply. The invention can assure the safety of the use of an electric appliance product such a tool machine.
