BITUO’s selection of electrical auto switch and relays. Our Dot Light Auto Switch line includes toggle switches, rocker switches, high power battery switches, marine grade switches, keyed switches, push and pull switches, and switch panels. We also carry 12 volts automotive relays such as the standard 5 prong relays, as well as high amperage relays up to 200 amps, and solenoids for high power switching. Our toggle switches and rocker switches are dual voltage and can be used for either low voltage 12 volt and 24 volts DC switching or 120-240 volts AC switching. They are also available in different switching configurations such as SPST (single pole single throw), SPDT (single pole double throw), DPST (double pole single throw), and DPDT (double pole double throw). On, Off, and Momentary On switch functions are available for the toggle switches and rocker switches as well.

Disconnect switches cut off the electrical load going from the battery to the rest of the system. They are commonly used for safety and avoiding battery drain when a vehicle is idle for a period of time.

Most of the common types of switches come in different styles, such as toggle, rocker, slider, or push-button. The style usually does not affect the switch function and wiring. While switches usually are used for lights, they can be used to turn electrical current on or off for nearly any electrical device

Automotive companies worldwide have come to rely upon BITUO’s reliable, high-performance, high-quality switches to power their innovative applications and designs. Features such as tight product tolerances, haptic-on-demand, acoustical adaptation, environmental & process sealing and mechanical or electrical interface integration are the core values of automotive switching – and BITUO is known for successfully delivering these to customers for more than 10 years.
