Gravity Limit Switch is widely used in EOT cranes to control and limit the movement of lifting mechanisms within a predefined range. It ensures safe operation by automatically disconnecting the motor when the limit position is reached.
The switch operates through a weight-based mechanism. When the crane’s snatch block reaches its top position, it activates a lever connected to a shaft. This movement rotates the cam mechanism, which opens the contacts and stops the motor. The system automatically resets when the lever returns to its original position due to gravitational force.
Features:
Usage/Application: Machine Tools

Rated Voltage: 440 VAC
Current Rating: 40 Amp
Switch Positions: 2 to 4
Minimum Order Quantity: 2 Piece
Rotary Gear Limit Switch (GRLS) is designed to automatically cut off motor supply when the moving load reaches its extreme end positions. It ensures safe and controlled operation in industrial machinery and crane systems.
The driving motion is transmitted through a worm gear mechanism via a worm shaft. The rotation is further transferred to the switching mechanism using adjustable cams, allowing precise control over movement limits.
Features:
Contact Configuration: NC
Switch Type: Rotary Limit Switch
Rated Voltage: 240 VAC
Brand: Sai Tools
Country of Origin: Made in India
Minimum Order Quantity: 100 Piece
Worm Drive Limit Switch (GRLS FG 50) is a compact and efficient rotary limit switch designed to control and limit the movement of loads in industrial applications. It ensures safe operation by automatically cutting off motor supply when the load reaches its extreme end positions.
The switch operates using a worm gear mechanism with multiple ratio options such as 12.5, 25, 50 and 100:1, allowing precise control over motion limits. It is widely used in cranes and material handling systems for reliable and accurate performance.
