Rapid Delivery for Rotary Switch - LW31-Rotary Switch – Leyu
Rapid Delivery for Rotary Switch - LW31-Rotary Switch – Leyu Detail:
Common band switches and shift switches of multimeters are rotary switches, and there are two structures: one is BBM (Break Before Make) contact type, which is characterized in that the moving contact first disconnects the front contact when changing positions After connecting the rear contact, there is a state of disconnection with the front and rear contacts: the other is the MBB (Make Before Break) contact type, which is characterized by a state where the moving contact is in contact with both the front and rear contacts when changing positions. . Then disconnect the front contact and keep in contact with the rear contact. In the circuit design, the appropriate rotary switch should be selected according to the purpose of the circuit and the safety of the circuit.
