Abstract

Die erfindungsgemäße Schutzkappe (1) dient zur Abdichtung der Handhabe bzw. des Knebels eines Drehschalters. Sie besteht aus elastischem Material und weist einen Innenraum der Gestalt auf, daß die Handhabe in dem bei ihrer Betätigung eingenommenen Raum ohne Rückstellungsdrehmoment durch die Schutzkappe (1) frei beweglich ist.

Figure 00000001
The protective cap (1) according to the invention serves to seal the handle or toggle of a rotary switch. It consists of elastic material and has an interior such that the handle can move freely through the protective cap (1) in the space occupied when it is actuated, without any restoring torque.
