Toggle switches are a special type of electrical switches typically used for on-off control of single circuits. The ET21SD1ABE is a double-pole, single-throw (DPST) electromechanical toggle switch designed for general-purpose applications in the automotive, telecoms, instrumentation and heating & ventilation sectors.

This switch is designed with a double pole throw to allow for the switching of two separate circuits. Its body features a UL-rated polyester dielectric for superior flame retardance, and its toggle is made from polyamide 66 material with glass fiber, achieving an IP67 rating for dust and water seal protection. The ET21SD1ABE is rated at 10A/400V AC and 0.3A/30V DC and is supplied with screw, solder or PC board connections.

The ET21SD1ABE works by the contact between the actuator and the switch body. Rather than a slide switch, toggle switches have actuators with slightly different shapes, such as a lever or rocker. When the actuator is in the “off” position, the contacts between the switch body and the actuator break and the circuit is open. When the actuator is in the “on” position, the contacts between the switch body and the actuator close and the circuit is closed.

This specific switch has a combination of features that make it suitable for a variety of applications. The combination of its multiple circuit capability and IP67 rating allows for use in heavier-duty applications for general purpose, automotive, telecoms, instrumentation and heating & ventilation sectors. The screw, solder and PC board terminals make it an ideal choice in a wide range of applications, from automotive signal boards and telecoms equipment to industrial automation systems.

In summary, the ET21SD1ABE is a double-pole, single-throw electromechanical toggle switch with a UL-rated polyester dielectric and polyamide 66 toggle, achieving an IP67 rating for dust and water seal protection. With its double-pole throw and a range of connections, it is suitable for heavier-duty use in automotive, telecoms, instrumentation and heating & ventilation applications.
