A Rotary Limit Switch is an electromechanical device used to monitor and control the rotary movement of industrial machines like cranes, hoists, wind turbines, winches, elevators, and other equipment with rotating shafts. It uses gear-driven cams to actuate electrical switches, stopping or reversing a motor when a preset position or number of rotations is reached.

A Crossbar Lever Limit Switch is a type of mechanical position-sensing switch used in industrial automation, cranes, hoists, elevators, and material handling systems. It operates by detecting the physical movement of a lever arm, usually in a horizontal (crossbar) configuration, to trigger or interrupt electrical circuits based on equipment position.

A Rotary Gear Limit Switch is a mechanical safety and control device used primarily in cranes, hoists, winches, and industrial lifting equipment. It operates by converting rotational motion into mechanical switching action, enabling the system to control or limit movement—such as the upper and lower travel limits of a hoist drum.

A Counterweight Limit Switch is a type of mechanical safety switch used in hoists, elevators, cranes, and other vertical lifting systems. It relies on a gravity-based counterweight mechanism to detect excessive movement (typically overtravel) and interrupt power or activate alarms when limits are exceeded—especially in hoisting drums or elevators.

A crane limit switch is a crucial electromechanical safety device used in overhead cranes, hoists, and similar lifting equipment to restrict motion beyond a defined limit. It automatically stops or changes the direction of motion to prevent over-travel, mechanical failure, or hazards.
