Rocker Switches

Rocker switches are devices that are used to control currents and come in a variety of shapes, sizes, and colors. The B123J1WQ2 is no exception. It is a single-pole, double-throw (SPDT) snap-action rocker switch with form “C” contacts.

The B123J1WQ2 rocker switch is primarily used as a control switch in applications requiring frequent switching, such as lighting controls, HVAC systems, and audio/video equipment. The switch boasts a light-duty 2 A 250 V AC and a heavy-duty 10 A 125 V AC with a mechanical life of 30,000 cycles. It also features a continuous rating of 15 A with a UL94 V-2 flammability rating and a temperature range of -20°C (-4°F) to +65°C (150°F).

In addition to its high performance switches and other products, the B123J1WQ2 also offers a variety of accessories to help simplify installations and decrease costs. These accessories include Clean Connect Removable Terminal Blocks for mounting as well as Terminal Covers and Knob Covers for protection.

Working Principle

The B123J1WQ2 rocker switch has two sets of contacts. The first is a double-throw (DT) contact switch, which is the main switching element. The second is a single-pole, single-throw (SPST) contact switch, which is used to keep the main DT switch engaged. When the DT switch is pressed down, the contacts close and make an electrical connection. When the SPST switch is released, the DT switch is opened and the contacts break.

This type of switch is designed to work in momentary or latching operating modes. In momentary mode, the switch only remains activated for as long as it is pressed down. In latching mode, the switch remains in its last position when it is released, so it must be reset in order to change the position of the contacts.

The B123J1WQ2 switch is designed for reliable, high performance switching and also has low contact bounce characteristics. This type of switch is ideal for applications that require frequent switching, such as emergency lighting, HVAC systems, and audio/video equipment.
