This Product Selection Guide contains information to help select products in the Cable Pull Switches category on DigiKey.com
Cable Pull Switches can be activated by pulling, pushing, or a broken wire rope in any direction at any time to turn off the power on a machine. The operating force is 3175gf, 5608gf, 10197gf, 12236 – 18354gf, 12746gf, 15295gf, 20394gf, and 30081 – 39768gf with a maximum cable length from 5m, 10m, 20m, 25m, 35m, 60m, 100m, and 130m.
SelectionCharacteristics
Circuit: Describes device function in terms of a number of poles and throws, as is typical for mechanical switches. For more information please see: Switch Basics, Examples of Pole and Throw
Switch Function: Refers to the specific operation or behavior of a switch, indicating the primary purpose or mode of operation. For more information please see: Switch Basics, Examples of Pole and Throw
Current Rating (Amps): Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Voltage Rating - AC: Typically this represents the maximum AC voltage to which a device will meet its given specifications. Exceeding this voltage may damage the device and/or other system components.
Voltage Rating - DC: Typically this represents the maximum DC voltage to which a device will meet its given specifications. Exceeding this voltage may damage the device and/or other system components.
Maximum Cable Length: Maximum cable span to provide the optimal pull force and pull distance.
Features: These are different capabilities of the device such as explosion proof or lighted indicator.
Operating Force: Characterizes the force that must be applied to a device’s actuator to cause a change of device state or output, measured under manufacturer-defined test conditions.
Ingress Protection: IP (Ingress Protection) ratings such as (IP20, IP65, IP67, etc.) define how likely water and dirt will get into the system. The first number represents dirt and solid contaminants while the second represents water and liquids.
IP Ratings
| Solids | Liquids | |
|---|---|---|
| 1 | Protected against solids larger than 50mm. | Protected against vertically falling drops of water. Limited Ingress permitted. |
| 2 | Protected against solids larger than 12.5mm. | Protected against vertically falling drops of water with the enclosure tilted up to 15 degrees from vertical. Limited ingress permitted. |
| 3 | Protected against solids larger than 2.5mm. | Protected against spraying water up to 60 degrees from vertical. Limited ingress permitted for 3 minutes. |
| 4 | Protected against solids larger than 1mm. | Protected against water splashed from any direction. Limited ingress permitted. |
| 5 | Protected against dust. Limited ingress of dust permitted. | Will not affect operation of equipment 2-8 hours. Protected against jets of water. Limited ingress permitted. |
| 6 | Dust tight. No ingress of dust 2-8 hours. | Protected against powerful jets of water. Limited ingress permitted. |
| 7 | ______________________ | Protected against the effects of immersion in 15cm-1m for 30 minutes. |
| 8 | ______________________ | Continuous immersion in water up to 3m for long periods of time. |
| 9 | ______________________ | Protected against high pressure jets of hot water. (30 seconds) |
| 9K | ______________________ | Protected against high pressure jets of hot water. (2 minutes) |
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
