Different Types of Rocker Switches Panel Explained

Rocker switches are among the most versatile and common control devices in modern automotive, marine, and industrial electrical systems. When grouped together in a panel, they let you organize and control multiple accessories — lights, pumps, relays, etc. But not all rocker switch panels are the same. There are many varieties depending on how the switches operate, how they are constructed, how many circuits they control, how they handle environmental factors like water and vibration, and what additional features they include. In this article, we’ll explore the different types of rocker switches and rocker switch panels, what distinguishes them, how to decide which to pick, and how YUJIEKEJ’s switch panel line reflects these options.

Basic Concepts: Poles, Throws, & Switching Action

Before diving into panel types, it helps to understand what defines a rocker switch at its core.

• Poles refer to how many separate circuits a switch can control. A single-pole switch controls one circuit; a double-pole can control two circuits simultaneously.
• Throws refer to how many ON positions (or selectable outputs) each pole has — i.e. how many different states the switch can place its pole(s) into. A Single Throw (ST) switch is essentially ON-OFF (one output). A Double Throw (DT) means it can route to one of two outputs.
• Switching action describes how the user interacts with the switch and whether it stays in the chosen position (maintained), or returns to its default when pressure is removed (momentary).

These parameters determine a lot about what a switch panel can do, how complicated wiring is, how many terminals are needed, etc.

Common Types of Rocker Switch Panels

When rocker switches are assembled into panels (multiple switches in a single unit or a housing), the types vary by a combination of:

• Switch type per gang (SPST, SPDT, DPDT, etc.)
• Electrical rating (current & voltage)
• Environmental protection (waterproofing, IP rating, vibration resistance)
• Additional features (illumination, LED indicators, backlight, USB ports, voltmeter)

Here are some typical kinds:

1. Simple On-Off Panels (SPST Panels)

These panels have rocker switches which are Single Pole, Single Throw (SPST) — each switch simply connects or disconnects power to a single accessory or circuit.

Features:

• Each rocker has two positions: ON or OFF.
• Very simple wiring. Each switch has two terminals (power in, power out).
• Ideal for accessories like dome lights, small LED strips, small pumps, etc. when you don’t need to switch between inputs.

YUJIEKEJ offers panels like these — e.g. 4-gang or 8-gang SPST switch panels. They often have features like LED backlights so you can see which ones are on in low light.

2. On-Off-On Panels (SPDT or Centre-Off)

These are panels with rocker switches that have three positions, typically On-Off-On.

• SPDT = Single Pole, Double Throw: One input, two possible outputs. For example, choose between two accessories or modes.
• Sometimes constructed with a centre-off position (neutral) so neither output is active, then two ON positions either side.

Used where you want to switch between two functions — say between low beam and high beam, or selecting between two power sources. Also handy when switching something like fan speed (if wired appropriately) or reversing direction on a motor (if that is required).

3. Double Pole Panels (DPST / DPDT Panels)

These are more complex panels where each switch can control two circuits simultaneously (double pole).

• DPST = Double Pole, Single Throw: Two circuits, each turning ON or OFF together with one switch. For example, you might want to break both the positive and negative leads of a circuit for safety or redundancy.
• DPDT = Double Pole, Double Throw: Each pole can connect to one of two outputs. Or used to swap between circuits or reverse polarity.

Panels with DPDT switches are less common in typical automotive accessory panels (due to complexity) but are found in industrial, marine, or specialized automotive setups.

4. Momentary / Latching / Pulse Panels

Some panels use momentary switches or pulse / momentary versions:

• Momentary: The switch only stays in the ON (or alternate) position as long as it is held, then returns. Useful for things like horn, momentary lighting, maybe temporary signals.
• Latching / Maintained: The usual ON-OFF type — stays in position until changed.

Panels may mix switch types (some maintained, some momentary) depending on function. For example, a panel might have an emergency light switch as momentary while other switches are maintained.

5. Illuminated / Indicator Switch Panels

Many rocker panels include illuminated switches:

• LED or lamp inside or behind the rocker to show when that circuit is ON.
• Backlight for night-visibility.
• Sometimes coloured LEDs to correspond with function (red for warning, blue/white for lighting, etc.).

Helps with usability in low light, especially in truck cabins or off-road vehicles. YUJIEKEJ has panels with RGB backlights or LED indicator rings.

Key Considerations When Choosing a Rocker Switch Panel

When selecting a rocker switch panel, here are important criteria to help pick the right type for your needs:

• Number of switches (gangs)
  How many accessories do you have now, and how many might you add in future? Picking a panel with spare switches is often worthwhile.
• Current rating per circuit
  What is the maximum load each circuit will carry? For high-draw accessories (lights, fans, pumps), you’ll want relays or thick internal switching, and switches + panel rated for the current.
• Voltage compatibility
  Most automotive uses are 12V (sometimes 24V). Make sure the panel and switches are rated for the system voltage.
• Switch type (pole/throw, momentary vs maintained)
  • If you just need ON/OFF: SPST works.
  • If you need toggling between two functions: SPDT / On-Off-On switches.
  • If controlling dual circuits with one switch or reversing polarity: DPST / DPDT.
  • If you need momentary action (e.g. for flashers, horn etc.), get switches with that function.
• Environmental factors
  • Waterproof or splash resistant if exposed.
  • Durable contacts, vibration resistance.
  • Quality housing, good sealing, protective covers.
• Additional features
  • Illumination / backlights / LED indicators.
  • USB / charging ports.
  • Voltmeter / system monitoring.
  • Built-in fuse protection or breakers for each circuit.
• Size, mounting style, layout
  Panel dimensions and cut-out size. Depth behind the panel (important if space is limited). Orientation and how easy it is to access.
• Cost vs reliability
  Sometimes a more expensive panel with sealed switches and heavy-duty relays will pay off in longevity, especially if used in harsh conditions.

Summary

Rocker switch panels come in many varieties: SPST for simple ON/OFF, SPDT for switching between circuits, DPDT and double-pole versions for more complex control, with maintained or momentary action, illuminated or non-illuminated, waterproof / rugged or basic, etc.

YUJIEKEJ’s product line reflects many of these options: multi-gang panels, illuminated switches, RGB/backlight, waterproof rating, relays, USB/voltmeter features. The trick is to match the panel to your specific needs: how many switches, what current, what environmental exposure, whether you need extra features.
