LW26-20 YH5/3 Chave Rotativa 20a 3 LEVELS 7 POSITIONS Voltage switching over Electrical Rotary switch Voltmeter Switch
Rotary switches LW26 series
The rotary switches LW26 series are produced for switching on/off electrical circuits with commutated current from
20 to 160A. They are designed on the bases of the rotor-eccentric switching on which is realized through turning
of the handle to 60 or 90 degrees. The normal operation is used for commutation of two, three or four conductor
systems. There are special rotary switches that switch on under given connection schemes and are used to
control motors, electric welding machines and other consumers.
