Product Overview
The ASCO 73-13568-A3 GO Switch Model 73 is a leverless limit switch designed for dependable position sensing without the external moving components found in conventional mechanical limit switches. The GO Switch design eliminates external levers, springs, cams, and reed elements, helping reduce components that can wear or fail during repeated operation.
The 73-13568-A3 uses non-contact end sensing with a 0.100 in sensing face housed within a sealed, one-piece 316L stainless steel body. This construction makes the switch suitable for demanding applications where durability and resistance to harsh operating conditions are important.
The switch provides an SPDT (Form C) contact arrangement, allowing it to be configured for normally open or normally closed operation. It can be used with both AC and DC circuits within its specified contact ratings of 2 A at 240 VAC, 3 A at 120 VAC, and 1 A at 24 VDC.
The Model 73 operates across a broad temperature range of -50 to 105 °C (-58 to 221 °F), making it suitable for industrial installations exposed to significant temperature variation.
For installation flexibility, the 73-13568-A3 supports 5/8"-18 or M18 mounting threads and 1/2" NPT or M20 conduit entry. These options make it suitable for valve and actuator position-feedback installations where a sealed, compact limit switch is required.

Who This Product Is Best For
The ASCO 73-13568-A3 is suited for industrial users requiring dependable position feedback, including:
- Valve and actuator position-feedback applications
- Industrial automation and process-control systems
- Harsh or washdown environments
- Applications replacing mechanical lever limit switches
- Installations requiring a sealed switch without external moving parts
- Industrial equipment where a 316L stainless steel housing is preferred
How to Specify & Commission It
- Confirm that the 5/8"-18 or M18 mounting thread and 1/2" NPT or M20 conduit entry are compatible with the installation.
- Mount the switch so the target approaches the specified 0.100 in end-sensing area correctly.
- Wire the SPDT contacts according to the required normally open or normally closed configuration and ensure the circuit remains within the specified AC/DC contact ratings.
- Cycle the valve, actuator, or mechanism and verify that the switch changes state at the required position.
