When using the switching switch to rotate the switch, we need to know his specific knowledge. What are the specific problems? Let's give you a detailed introduction.
Introduce some knowledge about switching switch
The first toggle switch is to drive the slider or slider sliding by toggling the switch handle, thereby controlling the connection and disconnection of the switch contact. The switching switch is divided into two types: unipolar bipolar and bipolar bipolar. It is mainly used for the control of power supply circuit and the switching of working state circuit.
Relevant knowledge of rotary switches:
The switching switch controls the connection and disconnection of the switch contacts by the switching handle. It can be divided into unipolar unit and multipolar multibit structure. The unipolar unit rotary switch is usually integrated with the rotary axis potentiometer, which synthesizes the volume control potentiometer with the switch.
Multi-pole multi-bit rotary switch is mainly used for switching the working circuit.
Knowledgeable products of key switch. Key switch is generally composed of handle, slide board, movable contactor, fixed terminal, pressure spring, shell, etc. It controls the connection and closure of movable contactor and fixed terminal contactor by pressing switch handle.
There are two types of key switch: single-key switch and multi-key combination switch. Single-key button switch is generally used as power switch in TV set. It is divided into two types: self-locking self-reset type (this kind of switch turns on self-locking when pressed, then opens and resets when pressed) and unlocked type (can't lock, turn on when pressed, and reset after loosening hands).
Multi-key combination key switch can be divided into self-locking, interlocking and unlock-free structures. Eight-button or twelve-button switches were used as program pre-selection switches in the early stage of television, while four-button switches were used as washing state selection switches in the early stage of wave-wheel washing machine.
What is a button switch button switch button switch is an old standard term, abbreviated as a button in Chinese. Button has unipolar or bipolar switch. It can be divided into start button, reset button, check button, control button and limit button according to its kinetic energy and use.
