certain waterproof effect, the basic can reach the IP65 waterproof level.
At the same time, it needs to use hard and durable metal material, with a
difference of 2 or 3 gears.
Structural characteristics of
There are two kinds of structure: one is BBM(Break Before Make) contact type,
which is characterized by the moving contact first disconnecting the front
contact and then connecting the back contact when transposing, during which
there is a state of disconnecting the front contact and the front contact: The
other is MBB(Make Before Break) contact type, which is characterized by the
moving contact has a state of contact with both the front and rear contacts when
transposition. Then disconnect the front contact and maintain contact with the
rear contact. In-circuit design, a suitable rotary switch should be selected
according to circuit use and circuit safety.
The working principle of
In a range is to change the resistance value, and then there is a contact
switch, which is the switch of the old TV and radio, the fan is a few gears,
connected to the fan windings of several groups of lead wire, by changing the
number of lines to change the speed, the principle, and potentiometer
What are the application scenarios?
