Switchable interface for power tools
Disclosed is a power tool including a control device and at least one electromechanical interface device for connecting at least one rechargeable battery to the machine tool and supplying the power tool with voltage from the rechargeable battery. The interface device includes at least a first terminal and a second terminal and can be set to at least one first position and to a second position; the first terminal can be used for supplying the power tool with voltage from the first rechargeable battery when the interface device is in the first position, and the second terminal can be used for supplying the power tool with voltage from the second rechargeable battery when the interface device is in the second position.
1. A power tool comprising:
a control device; and
at least one electromechanical interface device for connecting at least one rechargeable battery to the power tool and for supplying the power tool with voltage from the rechargeable battery, the interface device including at least one first terminal and a second terminal, the interface device being settable to at least one first position and to a second position, the first terminal being usable to supply the power tool with voltage from a first rechargeable battery when the interface device is set in the first position, and the second terminal being usable to supply the power tool with voltage from a second rechargeable battery when the interface device is set in the second position;
wherein the first terminal includes a first number of terminal elements, and the second terminal includes a second number of terminal elements, the first number of terminal elements corresponding to a first rechargeable battery contact element number of contact elements of the first rechargeable battery, and the second number of terminal elements corresponding to a second rechargeable battery contact element number of contact elements of the second rechargeable battery; and wherein the interface device includes a first connecting point and a second connecting point for connecting the interface device to the control device, the first connecting point having a first number of connecting elements, and the second connecting point having a second number of connecting elements, the first number of connecting elements corresponding to the first number of terminal elements, and the second number of connecting elements corresponding to the second number of terminal elements.
2. The power tool as recited in claim 1 wherein a first configuration for supplying the power tool with voltage from a first rechargeable battery is selected when the interface device is set in the first position and the first rechargeable battery is connected to the first terminal, and a second configuration for supplying the power tool with voltage from a second rechargeable battery is selected when the interface device is set in the second position and the second rechargeable battery is connected to the second terminal.
3. The power tool as recited in claim 1 wherein the first or second position of the interface device or the first or second rechargeable battery connected to the interface device is detectable based on a number of connections between the terminal elements of the first and second terminals and the connecting elements of connecting points of the interface device.
4. The power tool as recited in claim 1 wherein at least one first terminal element of the first terminal as well as at least one second terminal element of the second terminal is configured at least to receive information from the first rechargeable battery and the second rechargeable battery at the power tool, so that a first configuration for supplying the power tool with voltage from a first rechargeable battery or a second configuration for supplying the power tool with voltage from a second rechargeable battery is settable according to the particular first or second rechargeable battery connected.
5. The power tool as recited in claim 1 further comprising at least one microswitch for detecting whether the interface device is set to the first position or the second position.
