皮带错位开关用于监视传送带的位置和跟踪。它安装在输送机结构上并进行了调整，使辊臂与皮带的外边缘保持适当的距离和角度。当皮带偏离对准时，它会接触到辊致动器臂，该致动器臂使致动轴旋转，从而导致皮带失准开关发出警报信号。
致动轴在壳体内部有两个凸轮。每个凸轮都驱动一个独立的SPDT微动开关，以发出警报信号。第一个微动开关通过致动轴旋转10°来发出警告警报信号，从而使操作员能够在出现问题之前解决问题。第二个微动开关通过致动轴旋转20°来致动以发出关闭警报信号，以防止或最大程度地减少设备损坏。压路机臂具有内部不锈钢轴承。这使得该开关可以在皮带速度高达每分钟1250英尺的输送机上使用，并具有出色的使用寿命。
This belt misalignment switch is used to monitor the position and tracking of conveyor belts. It is mounted on the conveyor structure and adjusted so the roller arm is the proper distance and angle from the outside edge of the belt. When a belt drifts out of alignment it contacts the roller actuator arm which rotates the actuation shaft, causing the belt misalignment switch to send an alarm signal.
The actuation shaft has two cams inside the housing. Each cam actuates an independent SPDT micro-switch for alarm signals. The first micro-switch actuates with a 10° rotation of the actuation shaft for a warning alarm signal, allowing operators to address the situation before it becomes a problem. The second micro-switch actuates with a 20° rotation of the actuation shaft for a shut down alarm signal in order to prevent or minimize equipment damage. The roller arm has internal stainless steel bearings. This allows the switch to be used on conveyors with belt speeds up to 1250 feet per minute with outstanding service life.
