Pull-wire switches are suitable as transducers for starting machines or to open and close electrically-powered doors, gates and barriers.
Design and mode of operation
Pull-wire switches are actuated manually by pulling. There are variants with and without latching. The pull-wire switches without latching generate a switching impulse on actuation. With the devices with latching the switching impulse is maintained until repeated actuation.
An important feature for the selection of pull-wire switches are the mounting possibilities, wall or ceiling mounting.
All pull-wire switches presented in this chapter bear the CE mark according to the Low Voltage Directive 2014/35/EU.
