Abstract
An electrical switch for an electric tool with an electric motor including an actuating mechanism which can be adjusted between an initial position and a final position. The switch has a signaling device, which is operatively connected to the actuating mechanism, for generating a signal associated with the adjustment path of the actuating mechanism. The switch has a contact system, with the actuating mechanism having a switching effect on the contact system in one position, whereby the contact system is configured as a spring-action contact system.
Claims8
An electrical switch for an electric tool with an electric motor, comprising an actuating mechanism that can be adjusted between an initial position and a final position, a signaling device that is operatively connected to the actuating mechanism for generating a signal associated with an adjustment path of the actuating mechanism, a control device for operating the electric motor, and a contact system,
- wherein the actuating mechanism has a switching effect on the contact system in one position,
- the contact system is configured as a spring-action contact system having a snap-action movement,
- the contact system is the bridging contact system for the control device, and
- the actuating mechanism has a switching effect on the contact system in the final position such that the contact system is switched on so as to apply the full voltage to the electric motor.
