Electric switch

Abstract

The invention provides an electric switch. The electric switch comprises a contact system, an actuation element, an engaging latch, and an actuator. The actuation element moves between an initial position and an actuation position to switch and changeover the contact system. The actuation element is located in a direction of the initial position by a force of a return spring. The engaging latch locks the actuation element in the initial position or the actuation position. A non-manual unlocking between the actuation element and the engaging latch is performed by the actuator.

Description

technical field [0001] The invention relates to an electronic switch which can be closed manually and automatically, which is applied to an electric device. Background technique [0002] Electrical devices consume energy in order to perform various functions. These electrical installations must comply with Directive 2009 / 125 / EC of the European Parliament of 21 October 2009. The directive aims to establish a framework agreement on environmentally sound design requirements. Therefore, the respective electrical devices must provide an automatic shutdown function so that shutdown can be achieved through an external signal or self-control. In electrical installations with different energy consumption levels, this automatic shutdown relates in particular to the highest energy consumption level. For example, the exhaust hood is provided with multiple switches to light up the light source and correspond to different exhaust rates, that is, different energy consumption levels. In...
