Switching arrangement
A switch assembly has two contacts; a switch having an open position in which the contacts are electrically separated from one another; and a switch status detector positioned remotely from the switch.
1. A switch assembly comprising:
two contacts;
a switch including a contact bridge, a motor connected to the contact bridge, and an armature connected to the contact bridge, the switch having an open position in which the contacts are electrically separated from one another and a closed position in which the contacts are in electrical contact with each other through the contact bridge, the armature having a distal end positioned opposite the contact bridge that is displaced by the motor when the switch transitions from the open to the closed position;
a switch status detector positioned remotely and electrically isolated from the switch, the motor positioned between the contact bridge and the switch status detector; and
a switching device having a switch housing into which the switch and two contacts are positioned, a wall of the switch housing having a signal-permeable wall region, the distal end of the armature is positioned in the switch housing proximate to the signal-permeable wall region and the switch status detector is positioned outside the switch housing proximate to the signal-permeable wall region.
2. The switch assembly according to claim 1 , wherein the switch status detector is positioned to face the motor.
3. The switch assembly according to claim 1 , wherein the switch includes a coil and the armature is positioned in the coil.
4. The switch assembly according to claim 3 , wherein a position of the armature is detected in a contact-free manner by the switch status detector.
5. The switch assembly according to claim 1 , wherein the closed position is detected by the switch status detector in a contact-free manner.
6. The switch assembly according to claim 1 , further comprising:
a high-voltage housing into which the contacts are positioned; and
a low-voltage housing into which the switch status detector is positioned, the high-voltage housing or the low-voltage housing being gas- or liquid-tight.
7. The switch assembly according to claim 1 , further comprising a housing having:
a high-voltage region into which the contacts are positioned, and
a low-voltage region into which the switch status detector is positioned.
8. The switch assembly according to claim 1 , wherein the switch status detector is an optical sensor.
9. The switch assembly according to claim 1 , wherein the switch status detector includes a signal output having:
a first signal when the switch is in the rest position, and
a second signal different from the first signal when the switch is in a position other than the rest position.
