Gear switch definition
Rotary switch applies the combination mode of multiple contact points of
transfer switch and multiple circuit combinations to realize the selection of
the same or different functions, so as to control and adjust household or
commercial electric ovens and other electrical appliances.
2. Structure of gear switch
The gear switch is also a rotary switch, including adjusting shaft,
switch body, cam, terminal and contact piece. The adjusting shaft is connected
with the cam, the cam is embedded in the main body of the switch, and the
terminals and contacts are installed in the main body according to the function
setting.
