  • Publication number: 20080083601
    Abstract: A power handle module encloses rechargeable batteries which can be used to power a number of modular special-purpose tools which may be mounted to the power handle module. The power handle module includes a hand grip, a trigger switch operated by a trigger and a first connector for engagement with a second connector on the special-purpose tool. An interlock operator on the handle module may be moved between a guard position where it resists pressure to move the trigger and at least one armed position, in which position it allows the trigger to be pressed. A secondary switch is mounted within the power handle module. When the special-purpose tool is a fastener driver the secondary switch controls direction of rotation of the motor on the tool.

  • Patent number: 7019233
    Abstract: The invention relates to a closing device consisting of a grip housing (10) containing a pivotably mounted grip flap (12). Said grip flap (12) is loaded by means of a restoring force (38) in the direction of its neutral position (12.1), against which force the manual actuation of the grip flap (12) must be carried out. Furthermore, an electrical switch (20) is associated with the grip housing (10), said switch comprising a spring-loaded (28) contact actuator (24). In order to provide a compact, cost-effective closing device, the restoring force (38) of the grip flap (12) can be directly generated by the spring-loading (28) of the contact actuator (24) of the electrical switch (20). In this way, separate springs are not required for the grip flap (12).

  • Patent number: 6664490
    Abstract: An AC/DC switch for electric power tools avoids bouncing when turned on, but assures quick cutting-off of heavy current. Operation does not vary with age, as might be caused by wearing of projections of the switching mechanism and/or inconsistency in spring material. A reversal spring quickly switches the mechanism on and off so that the movable contacts are brought close to the stationary contacts before the turning-on, thereby permitting the turning-on subsequent to traverse of the reversal point without bouncing of the movable contacts from the stationary contacts, and preventing movement of the movable contacts before reversal spring has stored increased energy, thus allowing quick release of stored energy to make the movable contacts leave the stationary contacts at a speed sufficient to prevent electric arcs between the movable and stationary contacts, and hence prevent the wearing of the contacts.

  • Patent number: 6259047
    Abstract: A power tool includes a motor and a switch device for starting and stopping the motor. The switch device includes an operation member and an on-operation prevention device. The operation member can pivot about a pivotal axis between an on position and an off position and has an on-operation arm and an off-operation arm on either side of the pivotal axis for operation by an operator. The on-operation prevention device serves to prevent the operation member from moving from the off position to the on position and to permit the operation member to move from the off position to the on position.
