HUBBELL WIRING DEVICE-KELLEMS Rocker Switches. They require pressure to open and close a circuit, to reduce accidental activation. MIL-S-22885/92 - This specification sheet is approved for use by Naval Electronic Systems Command, Department of the Navy, and is available for use by all Departments and Agencies of the Department of Defense. Rocker switches are panel-mounted switches that are used with appliances, light control, power tools, industrial machines, motor, and surge protection. FeaturesĮIA-520D000 - This sectional specification relates to the toggle, paddle and rocker operated family of special-use electro-mechanical switches of certified quality. Most rocker switch bases and rocker switch actuators are made of plastic, thermoplastic, or metal materials. You can have an interior light that is on when the door is. Important specifications for rocker switches include dimensions, electrical ratings, terminal types, materials and features. Reverse Momentary Switch (Off When Pressed) The door of a model car, place one in the Door Jam. Three-position momentary center-NEUTRAL rocker switches have a center position that can perform an OFF or NEUTRAL function. Momentary OFF - describes contacts which establish a circuit when the rocker switch is in the normal, closed (NC) position.Īlternate ON/OFF - describes a switch where the first actuation turns the rocker switch ON and the second actuation turns the rocker switch OFF.
Momentary ON - describes contacts which interrupt the circuit when the rocker switch is in the normal, open (NO) position. Three-position rocker switches have a center position that may or may not perform an OFF function. ON/OF rocker switches have separate ON and OFF functions and work like light switches. Maintained-contact rocker switches are described as: A normally closed (NC) rocker switch has contacts that are closed or connected in their unactuated (normal) position. They usually have six terminals are available in both momentary and maintained contact versions.Ī normally open (NO) rocker switch has contacts that are open or disconnected in their unactuated (normal) position. They usually have four terminals.ĭPDT rocker switches make or break the connection of two conductors to two separate circuits. SPDT switches are sometimes called three-way switches.ĭPST rocker switches make or break the connection of two circuit conductors in a single branch circuit. These switches usually have three terminals and are commonly used in pairs. SPDT rocker switches make or break the connection of a single conductor with either of two other single conductors. This switch type typically has two terminals and is referred to as a single-pole switch. SPST rocker switches make or break the connection of a single conductor in a single branch circuit. Rocker 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.
