Safety limit switch and ordinary limit switch and advantages

First, what is the difference between the safety limit switch and the ordinary limit switch

Limit switch is to limit the motion limit position of mechanical equipment electrical switch, generally can be divided into two kinds of safety limit switch and ordinary limit switch, ordinary limit switch is a universal limit switch, compared with the safety limit switch, the main difference is:

1, the safety limit switch has a direct open circuit action device (forced disconnect contact), which means that even if the contact bonding occurs, because the switch structure can forcibly disconnect the bonding section, the dangerous section (load) can always be stopped, and the device will operate at the safe end.

2, the ordinary limit switch does not have this structure, so if the contact bonding will continue to supply power, the dangerous section (load) naturally can not stop, the device will continue to operate in the dangerous section.

For places with high safety requirements, priority should be given to the safety limit switch.

Second, what are the advantages of the safety limit switch

Safety limit switch is mainly composed of switch components, switch actuators and transmission parts, mostly used in large-scale industrial production and some living appliances, which has the following advantages:

1, no matter what kind of material, as long as the contact operating force reaches a certain value, you can touch the switch and connect the power supply.

2, the contact output mode can be different with the external voltage and the output is different, there will be no leakage phenomenon.

3, will not be affected by adjacent sensors, the output is stable.

4. The shell and drive mechanism of the safety limit switch are made of strong materials, which can withstand great load and impact.
