Abstract

A work apparatus has a first and a second assembly. The second assembly is mounted movably in relation to the first assembly via at least one antivibration element. Formed between the first assembly and the second assembly is a vibration gap, which is bridged by the antivibration element. The work apparatus has a switch, for actuation by an operator, which includes a first contact element and a second contact element. When the switch is closed, the first contact element and the second contact element contact each other. When the switch is open, the first and second contact element do not establish an electrically conductive contact. The second contact element is part of the second assembly. The first contact element is part of the first assembly and, when the switch is closed, the first contact element and the second contact element bridge the vibration gap between the first and second assembly.
