A rocker switch is an electrical on/off switch . This rocking mechanism will either connect or disconnect an electrical circuit. Guozhi’s selection of rocker switches includes subminiature, miniature and power, providing an extensive range for printed circuit board through-hole, surface mount and panel mount applications. Models are available in illuminated and sealed/waterproof versions, with SPST, SPDT, DPST, DPDT, 3PDT and 4DPT functionality.

As a type of connector, terminal blocks are used to achieve electrical connections and are an important component in the electrical industry. Application scope: aerospace, rail transit, ships, mining machinery, metallurgy and chemical industry, power communications, electrical control, security, power supply, home appliances and lighting, etc.

A pin header is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm , though available in many spacings（1.27mm, 2.0mm, 3.96mm,5.08 mm ) Male pin headers are cost-effective due to their simplicity. The female header are available to mate.

Tactile switches are electronic on/off switches, buttons, or domes that momentarily complete a circuit when the tactile button is pressed. Applications including: automotive (air bags, heating/AC, door handles, column switches) aerospace (main cabin lights, flight attendant buttons) consumer (cell phones, headsets, remote controls, wearable electronics) medical (hearing aids, health diagnostics, portable equipment) industrial (control panels, instrumentation, power supplies) computer (keyboards) handheld applications (power and selection switches, volume control, keyfobs)

USB standard A connector for host controllers in computers and hubs USB standard B connector, designed for USB peripherals such as printers, upstream ports on hubs, or other larger peripherals The USB Type-C connector is the latest USB interface to ship with the new USB 3.1 standard and can be used for host controller ports and devices using upstream slots Micro USB B connector is essentially a scaled-down form of microUSB that allows mobile devices to become slimmer while still retaining the ability to connect to computers and other hubs.

Solar connectors are used to connect solar panels to other panels, batteries and junction boxes. The most common type of solar connector is the MC4 connector, a standardised single pole connector that has built in strain relief and interlocks. These interlocks ensure a secure mating and protection against accidental release between plugs and sockets. As they are often used outside MC4 connectors are weather-proof, and are paired with cable that is double-insulated and UV resistant. Branch Connectors are available to assist the connection of solar panels in parallel or series, for example linking multiple panels to a single battery for increased power.
