Rotary gear limit switches are used to control the movement of crane or hoists when its necessary to measure movement based on the rotation angle and/or the number of shaft revolutions, providing upper, lower and/or intermediate limits for moving machinery and mechanisms.
Usually connected to the motor shaft, the rotary gear limit switch uses a series of gears and cams to activate a micro switch when the appropriate number of rotations is reached. This is generally used to stop the motion when a moving load has reached the desired position or final positions.
