Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.

SOLH 3V series 3/2-way pneumatic solenoid directional control valves are engineered with both direct-acting and pilot-operated structures, tailor-made for driving single-acting spring return cylinders and switching vacuum pneumatic circuits. Available in Normally Closed (NC) and Normally Open (NO) configurations, this series adopts high-strength lightweight aluminum alloy valve bodies with compact layout, rapid response and IP65 dustproof & waterproof protection grade, acting as the standard core control component for small and medium-sized pneumatic automation systems. The port layout follows universal industry standards: P for main air inlet, A for execution working port connecting cylinders or vacuum suckers, R for exhaust port matched with silencers to lower operational noise. Direct-acting 3V1 and 3V2 variants support reliable zero-pressure startup within 0~0.8 MPa with switching response under 0.05s, perfectly fit for low-pressure gas pipelines and negative-pressure vacuum control scenarios. Pilot-operated 3V100/3V200/3V300 series features larger flow capacity and lower coil power consumption, requiring a minimum inlet pressure of 0.15 MPa for stable switching to satisfy high-flow conventional pneumatic loops. Equipped with a thimble-style manual override button for convenient on-site debugging during installation and maintenance, the whole series supports oil-free operation with stable sealing performance. Multiple thread specifications including M5, G1/8, G1/4 and G3/8 are optional, paired with mainstream global AC & DC voltages and two wiring modes of DIN socket and flying leads. It can directly replace traditional 3A air pilot valves and 3L hand pull valves without structural modification, widely deployed in workpiece clamping jacking mechanisms, vacuum adsorption switching, pneumatic interlock protection and inching control of small actuators.

Switchgear Secondary Installation: Product Details and Applications Product Overview Switchgear secondary installation refers to the configuration, interconnection, and installation of secondary circuits and components within a switchgear system. Secondary circuits manage control, protection, metering, and signaling functions, ensuring efficient and safe electrical distribution. These installations typically involve control cables, auxiliary relays, secondary terminals, wiring looms, sensors, and protective devices like current transformers (CTs) and voltage transformers (VTs). They complement the primary system, facilitating effective monitoring and control over medium and low-voltage networks.
