Abstract: An electrical switch includes a rotary switch actuator device, and an actuator locking device. The actuator locking device inhibits the rotation of the rotary switch actuator device when the contacts of the switch are closed. Only when the operator tries to open the switch with an operating handle and the contacts do actually open, a lock release device will release the actuator locking device, and allow the operator to move the operator handle to the position corresponding to the open condition. When the contacts do not open, e.g., because they are welded, the actuator locking device will remain locked and the handle movement is blocked. This provides a robust and safe switch that never gives a false “OFF” indication.

Abstract: A gas-circuit breaker includes a cylinder, a stationary piston, and a moving piston. The cylinder has a moving contact that is fixed on one end of a rod and has a gas exhaust that faces a stationary contact. The rod is inserted into the cylinder.

The moving piston partitions the puffer chamber into a first puffer chamber and a second puffer chamber. Sliding of the moving piston changes the capacity of the first puffer chamber and the second puffer chamber according to the difference in pressure in the first puffer chamber and the second puffer chamber.
