Product Description
LW26-20/D202.2 for machinery of product details:
Operating principle
The handle drives the spindle and cam to push the contact to connect or disconnect. Due to the different shape of the cam, when the handle is in a different position, the contact's anastomosis is different, so as to achieve the purpose of converting the circuit.
Functional characteristics
Diversified control functions: it can be used as a circuit control switch, test equipment switch, motor control switch and master command control switch, and welding machine changeover switch, and can realise a variety of circuit control functions, such as manually switching on or off the circuit infrequently, as a control or conversion.
Reliability: Small, compact design, good choice of materials, good insulation, flexible switching, safe and reliable, novel design.
