Einhebel

Einhebel is a German noun meaning one lever. It describes a control mechanism that is actuated by a single lever. The term is used in technical and industrial language and appears in compound forms such as Einhebelarmatur (single-lever faucet), Einhebelbedienung (one-lever operation), or Einhebelregelung (single-lever control). Etymologically it combines ein (one) and Hebel (lever).

In plumbing and sanitary engineering, Einhebelarmatur refers to a faucet or mixer operated with one handle that simultaneously regulates water flow and temperature. Such designs are common in kitchens and bathrooms due to their compact footprint and straightforward operation. One-lever controls are also found in other systems where quick, single-handed adjustment is desirable.

In broader industrial and mechanical contexts, Einhebel may describe any device or control that uses a single lever to set a parameter or drive a function. This can include certain machine controls, ergonomic interfaces, or safety mechanisms where a lone actuator is preferred for simplicity and speed.

Advantages of Einhebel designs typically include reduced component count, easier cleaning, and intuitive operation. Limitations can include less precise control for fine-tuning and greater wear or mechanical play at the pivot over time, since all adjustments pass through a single linkage.
