Abstract
An apparatus comprising an electrical device having a first connection terminal, a second connection terminal and a holder for holding a voltage source having two voltage-source terminals. The holder has a first contact, a second contact and a third contact for cooperation with the voltage-source terminals. Via these contacts the first connection terminal is connectable to one voltage-source terminal and the second connection terminal is connectable to the other voltage-source terminal. The holder is adapted to allow the first contact, the second contact and the third contact to engage simultaneously with the voltage-source terminals. When the voltage source is present the first contact and one of the two other contacts are in engagement with one of the voltage-source terminals, and the other contact, which is not in engagement with the first voltage-source terminal, is in engagement with the second voltage-source terminal. The first contact is connected to the first connection terminal of the electrical device and the second contact and the third contact are connected to, respectively, a first input and a second input of a FET circuit. The FET circuit has an output connected to the second connection terminal of the electrical device.
