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

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.
