This square rocker switch is rated for up to 16 amps and accommodates four pins, typically used for double-pole circuits. The 4-pin configuration allows it to control two separate circuits simultaneously or support advanced wiring setups. It is made with durable materials, often featuring heat-resistant plastic and a reliable internal mechanism for long-lasting performance. The snap-fit design ensures easy installation on panels without the need for screws. Variants may include an illuminated rocker to indicate the on/off state, making it suitable for appliances, industrial machines, and electrical panels.
