Toggle Switch SPST SPDT DPST DPDT 250V AC 15A — E-TEN & BEM Series with Waterproof Cover

Start by identifying how many circuits you need to control and how many positions you need. SPST (Single Pole Single Throw) is the simplest ON-OFF switch for one circuit. SPDT (Single Pole Double Throw) lets you route one circuit to two outputs. DPST controls two circuits simultaneously with one throw. DPDT controls two circuits and can route each to two outputs — ideal for motor reversing or complex panel wiring.

For 2-position use, choose ON-OFF models (e.g., 1021, 1121, 1221, 1321). For 3-position use, choose ON-OFF-ON models (e.g., 1122, 1322, 123F, 223F).

These toggle switches are rated at 250V AC and 15A. This makes them suitable for general-purpose electrical panel wiring, automotive accessories, marine applications, and DIY control circuits. Always verify that your application's load does not exceed the rated current to ensure safe operation.

The standard toggle switch models are generally designed for indoor or protected panel use. For outdoor, marine, or moisture-prone environments, we recommend pairing your switch with the optional Waterproof Cover available as a separate variant. The cover typically provides a protective boot that shields the toggle from water ingress, making it suitable for boat dashboards, outdoor enclosures, and similar applications.

Both E-TEN and BEM series follow the same pole/throw configuration naming convention (e.g., 1021 = SPST ON-OFF, 1122 = SPDT ON-OFF-ON). The BEM series generally features a slightly different body construction and terminal layout compared to E-TEN, which may affect panel cutout fit and terminal spacing.

• Models with a "C" suffix (e.g., BEM-1021C) typically indicate a variant with a different actuator style or mounting configuration.
• Models with "F" or "FC" suffix indicate a flat or flush actuator design.

Check the variant name carefully to match your panel requirements.

Panel cutout dimensions vary by model series. Standard toggle switches in this category typically require a round or rectangular cutout of approximately 12mm–13mm (≈1/2") in diameter for the mounting bushing. Always refer to the specific model's datasheet or contact us to confirm exact cutout dimensions before drilling your panel.

Yes, these switches are commonly used in car dashboard panels, boat control consoles, RV electrical systems, and custom automotive builds. They are generally compatible with 12V DC and 24V DC systems when used within their rated current capacity. For DC applications, the effective switching capacity may differ from the AC rating — in most cases, a 15A AC-rated switch can handle 10A–15A DC loads, but always verify with your specific wiring requirements.

A DPDT (Double Pole Double Throw) switch like the 1321 or 1322 model can be wired to reverse a DC motor by crossing the output terminals:

• Connect the positive supply to the center terminals of both poles.
• Wire one motor lead to the top terminal of Pole 1 and the bottom terminal of Pole 2.
• Wire the other motor lead to the bottom terminal of Pole 1 and the top terminal of Pole 2.

Flipping the switch reverses the current direction through the motor. For ON-OFF-ON models (1322), the center OFF position disconnects the motor entirely.
