A contact element that only produces one break point in the same pole to complete the opening or closing of its circuit. A13 Double-break point contact element
A contact element that uses two contacts in series in the same pole to complete the opening or closing of its circuit. A14 Connecting contact element
A contact element that closes a circuit when the switch is operated. A15 Disconnecting contact element
A contact element that disconnects a circuit when the switch is operated. A16 Conversion contact element
A contact element composed of a connecting contact element and a disconnecting contact element, 343

A push button switch with a maximum working voltage of 50VDC or AC and a maximum working current of less than 100mA. A3 Membrane switch
A panel switch with a certain operating function composed of any number of weak current push button switches and a membrane and printed board with operating symbols. A+ Knob switch
A switch operated by manual rotation,
Protective switch
A switch that can effectively prevent the intrusion of solid foreign matter and water. A6 Multi-pole switch
A micro-gap switch composed of two or more switch elements, operated by the same actuator, which can simultaneously connect or disconnect two or more circuits
A7 Multi-unit switch
A combination switch composed of two or more switch elements, each switch element has a mechanical operating system, and the drive between the switch elements can be mechanical or electromagnetic. A8 Touch switch
A micro-gap switch that can connect or disconnect the circuit by applying a very small force similar to touch to the switch by a finger or device. A9 High-reliability micro-gap switch
A micro-gap switch that takes reliability indicators into consideration when designing and assesses reliability indicators in product standards, A0 Contact
