Abstract
A high-voltage relay includes a magnetic drive assembly having a first yoke and a second yoke spaced apart from one another, and an armature driven by the magnetic drive assembly. The armature is a rocker having a first arm and a second arm extending away from the first yoke. The armature can be tilted between an open position and a switching position and is mounted on the first yoke. The first arm has a switching contact assembly. A magnetic circuit including the first yoke and the second yoke is closed in the switching position by the second arm.

A high-voltage relay, comprising:
- a magnetic drive assembly having a first yoke and a second yoke spaced apart from one another;
- an armature driven by the magnetic drive assembly, the armature is a rocker having a first arm and a second arm extending away from the first yoke, the armature can be tilted between an open position and a switching position and is mounted on the first yoke, the first arm has a switching contact assembly that is spaced apart from a first load terminal of the high-voltage relay in the open position and is in contact with the first load terminal of the high-voltage relay in the switching position, the switching contact assembly has a switching contact and an insulating element insulating the switching contact from the second arm, the insulating element has a base plate with a web, a magnetic circuit including the first yoke and the second yoke is closed in the switching position by the second arm extending between and contacting the first yoke and the second yoke;
- and
- a locking device limiting an amount of rotation of the armature away from the first yoke to a predetermined amount of rotation.
A high-voltage relay, comprising:
- a magnetic drive assembly having a first yoke and a second yoke spaced apart from one another;
- and
- an armature driven by the magnetic drive assembly, the armature is a rocker having a first arm and a second arm extending away from the first yoke, the armature can be tilted between an open position and a switching position and is mounted on the first yoke, the first arm has a switching contact assembly that is spaced apart from a first load terminal of the high-voltage relay in the open position and is in contact with the first load terminal of the high-voltage relay in the switching position, the switching contact assembly has a switching contact and an insulating element insulating the switching contact from the first arm, the insulating element has a base plate with a web that is received in a clamping receptacle of the first arm to attach the insulating element to the first arm, a magnetic circuit including the first yoke and the second yoke is closed in the switching position by the second arm extending between and contacting the first yoke and the second yoke.
