Abstract
An electric switch is provided. 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.
Claims12
An electric switch, comprising:
- a housing;
- a contact system;
- an actuation element moving between an initial position and an actuating position for switching or changeover the contacting system;
- the actuation element located in a direction of the initial position by a force of a return spring;
- an engaging latch interacting with a guiding curve of a heart-shaped switching groove arranged on the actuation element to make the actuation element locked in the actuation position;
- an actuator driving a non-manual unlocking of the actuation element on the engaging latch under control a drive mechanism;
- wherein the drive mechanism comprises a coil and a permanent magnet, when the coil is not driven, the permanent magnet is attracted by the coil and a uniform magnetic circuit is formed between the permanent magnet and the coil;
- when a current flows through the coil, a magnetic field is generated to repel the permanent magnet to dive the actuation element.
An electric switch, comprising:
- a housing;
- a contact system;
- an actuation element moving between an initial position and an actuating position for switching the contact system;
- the actuation element loaded in a direction of the initial position by a force of a return spring;
- an engaging latch interacting with a guiding curve of a heart-shaped switching groove arranged on the actuation element, and the actuation element driven to be locked in the actuation position;
- an actuator driving a mon-manual locking of the actuation element on the engaging latch under control a drive mechanism;
- wherein the drive mechanism comprises a coil and a permanent magnet, when a current flows through the coil, a magnetic field is generated to repel the permanent magnet, the permanent magnet is attracted by the coil to drive the actuator to move.
