Pull Wire Switch
Strict safety measures to prevent accidents in industries such as transport machinery, quarrying, power generation and wood processing have made the use of Anjin wire pull switches a necessary technology. Hazardous areas are defined as machine parts that are moving without safety protection. Compared with emergency push-button switches, the switch can be actuated at any point of the pulling money, thus realizing the safety protection effect.
Working principle:
The pull wire switch is fixed according to the installation instructions. When the switch is pretensioned, contacts 11-12 and 21-22 are turnedon. When the pull wire is pulled or disconnected, the contacts are forced apart while the state is locked, and unlocking can be achieved with a button or key.

Note:
Inductive load power factor=0.4 ( AC ) , time constant=7msec
The inrush current of the lamp load is 10 times of the steady
The inrush current of motor load is 6 times of the steady
