Rocker Switches Information

Show all Rocker Switches Manufacturers

15 AMPS @ 125 V AC with illuminated actuatorRocker switches are electrical switches actuated by a standard or dual rocker or paddle. They are available in different configurations including two-position On/Off, three-position, momentary, maintained and more.

Pole and Throw Configurations

SPST rocker switches make or break the connection of a single conductor in a single branch circuit. This switch type typically has two terminals and is referred to as a single-pole switch.

SPDT rocker switches make or break the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are commonly used in pairs. SPDT switches are sometimes called three-way switches.

DPST rocker switches make or break the connection of two circuit conductors in a single branch circuit. They usually have four terminals.

DPDT rocker switches make or break the connection of two conductors to two separate circuits. They usually have six terminals are available in both momentary and maintained contact versions.

A normally open (NO) rocker switch has contacts that are open or disconnected in their unactuated (normal) position. A normally closed (NC) rocker switch has contacts that are closed or connected in their unactuated (normal) position.

Switch Configurations

Maintained-contact rocker switches are described as:

  • ON/OFF
  • Three-position center-OFF
  • Three-position no center-OFF

ON/OF rocker switches have separate ON and OFF functions and work like light switches. Three-position rocker switches have a center position that may or may not perform an OFF function.

Switch Functions

Momentary ON - describes contacts which interrupt the circuit when the rocker switch is in the normal, open (NO) position.

Momentary OFF - describes contacts which establish a circuit when the rocker switch is in the normal, closed (NC) position.

The W-Series traditional appearance features complete IP68 protection, even below the panel, where the critical connection is made from your wiring harness.Alternate ON/OFF - describes a switch where the first actuation turns the rocker switch ON and the second actuation turns the rocker switch OFF.

Three-position momentary center-NEUTRAL rocker switches have a center position that can perform an OFF or NEUTRAL function.
