Abstract: The water discharge device (faucet) is provided with a pullout spray head (2) that may be pulled down from the curved pipe (3) and which spray head is provided with a discharge mouthpiece (5). A switching valve (8) is arranged within said spray head (2) whereby said switching valve (8) is positioned in a housing (7) that is dimensioned in such a manner that it may be grasped by the user with one hand. Said switching valve (8) may be actuated by an operating lever (6). Said operating lever (6) is a bail (U-shaped lever) that is pivotably mounted on a water-guiding part (24) and which in turn is connected to a switching arrangement (28) mounted in said housing (7) with which a valve member (9) of the diverting valve (28) may be moved in its longitudinal direction during movement of the bail (6). Said bail (6) is arranged in such a manner that it may be operated with the thumb of the hand that is grasping said housing (7).

Abstract: A meter provides an arrangement for the optional connection of its voltage circuit to a current path or to a calibration system. The arrangement includes an opening, provided in the housing of the meter for inserting a contact device connected to the calibration system, and a pivoting lever. On insertion of the contact device into the opening, the pivoting lever can be moved from an operating position, connecting the voltage circuit to the current path, into a calibration position connecting the voltage circuit to the calibration system. Consequently, the arrangement can be changed over between the operating position and the calibration position with a minimum possible cost.
