Principle
The Paddle Switch operating principle is simple. A unit is usually located through the bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle. When this paddle rotation is impeded by the material surrounding the paddle, the motor will stall and cause the micro switch to change state and indicate an alarm or control condition.
