Which Switch Do I Need?
Unsure which switch function is right for your project? Start with these simple questions, and we’ll help you find the perfect solution.
Do you need a switch to simply turn a single circuit ON or OFF?
Yes -> You likely need an ON-OFF (SPST) or ON-OFF (SPDT) switch.
Do you need a switch to toggle power between two different devices?
Yes -> You might need an ON-ON (SPDT) or ON-OFF-ON (SPDT) switch.
Do you need the switch to be active only when pressed, and then return to its original position?
Yes -> You need a Momentary switch function, such as (ON)-OFF or (ON)-OFF-(ON).
Does your device need to control two independent circuits simultaneously?
Yes -> You’ll likely need a DPDT or DPST switch function.
What voltage and amperage do you need?
Voltage (V):
- 12V DC (Most common for RV and marine applications)
- 24V DC (Common for heavy-duty vehicles and larger vessels)

- IP65: Protected from dust and can resist low-pressure water jets from any direction.
IP66: Completely protected from dust and resistant to powerful water jets.
IP68: Fully protected from dust and can withstand continuous immersion in water.
Operating Temperature:
- Provide a temperature range, for example: -25°C to +85°C.

Yellow
White
What kind of LED illumination do you require?
Single LED:
Illuminates when the switch is in the “on” position to indicate power.
Dual LED:
One light stays on for visibility in the dark, and a second light turns on to indicate the “on” state.
Non-Illuminated:
No lighting needed
Choosing the Right Switch
These switches are used for basic on/off operation of a single circuit.
On-Off Switch (SPST – Single Pole Single Throw): This is the most common type of switch. It simply connects or disconnects a single circuit. It’s used when you need to turn something on and have it stay on until you manually turn it off.
Best For: Turning on/off interior or exterior lighting, power to an accessory panel, or a single appliance.
(On)-Off Momentary Switch (SPST): This switch is only active while it’s being pressed. Once released, a spring returns it to the “off” position, disconnecting the circuit. The “On” is in parentheses to denote its momentary function.
Best For: Activating a horn, a siren, a momentary starter button, or a push-to-talk communication system.
These switches allow you to toggle power between two different circuits.
On-On Switch (SPDT – Single Pole Double Throw): This two-position switch connects a single circuit to one of two different outputs. It’s used when you need to switch between two states, but never have both on at the same time.
Best For: Toggling between two sets of navigation lights (e.g., bow and stern lights), or controlling high/low beam headlights.
These switches provide three distinct positions, offering greater control over your circuits.
On-Off-On Switch (SPDT): This three-position switch has a central “off” position and can activate a circuit on either the left or right side. It is used when you need to control one of two different accessories from a single switch, with a dedicated off state.
Best For: Switching between two bilge pumps, or controlling left and right side work lights.
(On)-Off-(On) Momentary Switch (SPDT): This spring-loaded switch returns to the “off” position when released from either side. This function is typically used for applications where brief, pulsed power is required in two different directions.
Best For: Powering a winch (in/out) or controlling an electric window (up/down).
These switches manage two completely separate circuits from a single rocker.
On-On-Off Switch (DPDT – Double Pole Double Throw): This three-position switch controls two circuits with two “on” states and a single “off” state. It’s useful when you need to switch two sets of accessories on and off with one switch.
Best For: Activating two separate pairs of spotlights at the same time, or managing two sets of fans from one switch.

Frequently Asked Questions
What do the lP ratings mean?
IP (ingress Protection) ratings specify the environmental protection the switch provides. IP66 protects against powerful water jets, lP67 protects against temporary immersion (up to im for 30 minutes), and IP68 protects against continuous immersion (beyond 1M depth).
What is the difference between momentary and latching switches?
Momentary and latching switches serve different purposes:
Momentary Switches (on): These switches return to their original position when released, like adoorbell button. They’re ideal for temporary actions such as horn activation or trim tabadjustment.
Latching Switches on: These switches maintain their position until manually switched again, like atypical light switch. They’re perfect for functions that need to stay on, such as navigation lightsor bilge pumps.
