  • Patent number: 6727450
    Abstract: An electrical switch is provided having at least one contact system having a switching contact movable between two switch positions, an operating member that acts on the switching contact, a slide hinged on the operating member, and delay means operatively connected to the switching contact in at least one of the two switch positions. The delay means delaying movement of the switching contact, and being arranged in an extension of the slide. The delay means, the operating member and the slide are arranged on a same side of the contact system.

  • Publication number: 20030010617
    Abstract: The intention relates to an electrical switch (1) for electrical handheld tools such as drills, angle grinders, circular saws, routers, hedge trimmers or the like, having at least one contact system (3) which has a switching contact (4) which can be moved between two switch positions, namely between a switched-off position and a switched-on position for switching, and has a stationary contact (5) which interacts with the switching contact (4) in the switched-on position. The switch (1) has an operating member (6) which acts on the switching contact (4) for switching. A delay means (8) is located in the switch (1) and is operatively connected to the switching contact (4), in particular in the switched-on position, in order to delay the switching movement to at least one of the two switching positions. The delay means (8) and the operating member (6) are arranged on the same side of the contact system (3).

  • Patent number: 6104105
    Abstract: An electrical switch includes a housing having first and second input connections for electrical connection to a voltage source and the housing further has first and second output connections for electrical connection to an electrical device. The second input connection has an electrical connecting part for connection to the second output connection. The electrical switch also has an operating element which can be moved manually and at least one contact system which includes a fixed contact and a contact rocker. The contact rocker has first and second lever arms and a rotating bearing. The first lever arm is in communication with the fixed contact. The fixed contact is directly connected to the first input connection. The operating element, during its movement, acts upon the second lever arm in such a way that the first lever arm can be placed against the fixed contact in order to close an electrical connection of the contact system.

  • Patent number: 4523176
    Abstract: An electrical switch comprises, in addition to its switching mechanism or mechanisms, a potentiometer including a potentiometer plate and a slider which is advantageously moved/simultaneously with the actuation of the switching mechanisms. The switch requires terminal elements not only for the switching mechanism or mechanisms but also for this potentiometer. Consequently, an electrical connection must be provided within the switch between the inner ends of the terminal elements and the potentiometer plate. In accordance with the invention, the potentiometer plate is connected to the terminal elements by slip-in attachment which not only ensures a safe hold but also effects the electrical contact. To this end, the potentiometer plate is inserted into slot-shaped seats of the terminal elements, which are prevented from being unduly enlarged by suitable means.

  • Patent number: 4044215
    Abstract: An electric switch comprises a closed switch housing which is adapted to contain the switch contacts which has a guide bore for guiding a shaft portion of a switch operating member or push button. An operating member lock included an exterior housing portion associated with the switch housing which has a lock guide channel and a lock member bore intercepting the guide channel. The lock member is movable in the bore to engage a lock actuator which is connected to the switch operating member and is displaceable in the lock guide channel. The lock member is engageable with the lock actuator when the switch operating member is in an actuated position in order to lock the lock member and the switch operating member against movement.
