We often say that the function of the electronic control handle is to convey the will of the person to the equipment through the directional operation of the hand, so that the equipment can complete the work specified by the equipment according to the intention of the operator.For example, we usually see the excavator on the side of the road, see the operator's two hands keep operating the excavator's arm and body, and achieve the final effect is the function of the electric control handle.
In some cases, however, a safety switch (DEADMAN), also known as an enable button, is placed on the handle to prevent the device from misacting by accidentally touching the handle.The feature is that the handle only works when DEADMAN is pressed, which prevents the device from misoperating and causing safety problems. Note that DEADMAN only works when the operator pinches the grip with both his middle and ring fingers [see photo].

The other button on the handle is called the TRIGGER button , and it acts like the TRIGGER of a gun.TRIGGER is when the operator holds his hand on the handle, the index finger is in a free state, and whether the TRIGGER needs to be triggered at this time depends on the needs of the operator.Generally, it is a unique function of the operating equipment. For example, after the relevant equipment is operated with the handle to the specified position, the point position is processed (common cases are shooting or opening the impact device to break the stone, etc.) [see photo].

In a word, press the DEADMAN button and the handle will turn on, thus the signal and action issued by the handle will be effective. The TRIGGER is to hold the handle and then perform fixed-point operation as needed.
