The ABB JSHD4-1-AC 2TLA019995R0100 is an ergonomic three-position enabling switch designed to allow controlled machine movement when an operator must work within or close to a hazardous machine area. Part of the ABB Jokab Safety JSHD4 range, it is particularly suited to troubleshooting, test running, programming, adjustment and other tasks where restricted machine operation is required under direct operator control.
The JSHD4 uses a three-position operating principle in which the machine can be enabled only when the control is deliberately held in its centre operating position. Releasing the device or squeezing it fully to the third position changes the safety contacts to stop or inhibit hazardous machine movement. This provides an intuitive safety function for situations where personnel need controlled access to machinery during commissioning, maintenance or fault finding.
The JSHD4-1-AC configuration combines the JSHD4-1 top section, which has no LEDs and no additional push-buttons, with an AC bottom section featuring a 5-pole M12 male connector. The complete assembly offers a compact handheld format, IP65 protection and straightforward connection to compatible machine safety control equipment.
Three-position enabling devices are used when an operator needs to perform tasks that require limited machine movement while normal protective measures such as guards or doors are open. With the ABB JSHD4-1-AC, the operator deliberately holds the actuator in its centre enabled position while performing the required task. If the operator releases the device or instinctively grips it fully, the enabling contacts change state so the safety control system can stop hazardous movement.
This operating principle makes the JSHD4-1-AC particularly suitable for machine commissioning and servicing activities where direct observation of moving equipment is necessary. The dual enabling channels can be monitored by compatible safety control equipment, while the M12-5 connection simplifies installation and replacement. Its straightforward configuration without LEDs or auxiliary push-buttons makes it an effective choice where the primary requirement is reliable three-position enabling control.

The ABB JSHD4-1-AC is a three-position enabling switch designed to permit controlled machine movement while an operator is working within or close to a hazardous area, such as during troubleshooting, test running, programming, commissioning or adjustment.
The device has three operating states. Hazardous machine movement can be enabled while the actuator is deliberately held in its centre operating position. Releasing the actuator or squeezing it fully into the third position changes the safety contacts so compatible safety control equipment can stop or inhibit machine movement.
The JSHD4-1-AC uses a 5-pole M12 male connector, providing a convenient connection for its enabling contacts to compatible machine safety equipment.
No. The JSHD4-1 top section has no LEDs and no additional push-buttons. This model is intended as a straightforward three-position enabling device with an M12-5 connection.
The ABB JSHD4-1-AC has an IP65 degree of protection, making it suitable for use in demanding industrial machine environments when correctly installed and connected.
ABB Jokab Safety JSHD4-1-AC enabling switches provide ergonomic three-position machine control for troubleshooting, programming, test running and maintenance, combining dual-channel enabling functionality with a convenient M12-5 connection and IP65 protection.
