Pushbutton switches are the most common type of switches, found in everyday appliances and other electrical devices. The PB400EEQR1BLK is a pushbutton switch with a wide range of applications and a very simple operating principle.

This pushbutton switch is available in two versions, with either momentary or continuous contact. Both types can withstand up to 40A at 250V ac. The momentary switch is normally used to switch a circuit on or off from a momentary action, whereas the continuous contact version is a notched switch that remains in position after actuation for continuous operation.

The PB400EEQR1BLK is an illuminated switch with three poles: common, normally open and normally closed. An integrated LED illuminates when the switch is in the on position, allowing for clear and easy reading of the switch’s status. In addition, it can be supplied with pre-wiring, which helps further reduce installation costs.

In terms of the switch’s size, it is slightly larger than other similar products on the market, measuring 74.62 x 74.62 x 41.90 mm. Its two-part body construction makes it ideal for both surface and panel mounting. The strong plastic housing is impervious to dust and oil, making it highly resistant to corrosion, while the gold-plated contacts ensure low contact resistance. The PB400EEQR1BLK is suitable for use in a wide range of environments, including wet and hazardous areas.

In terms of its working principle, the PB400EEQR1BLK pushbutton switch uses very simple mechanics to perform its job. When the actuator (pushbutton) is pressed, the internal springs force the contacts to close, thereby completing the electrical circuit. This action will then open or close the circuit, depending on whether it is a momentary or continuous contact switch. When the actuator is released, the springs will restore the switch to its initial, resting state.

The PB400EEQR1BLK is a very versatile switch, offering a wide range of applications. It can be used wherever a normally open or closed switch is required, such as home appliances, light and fan control systems, and industrial automation processes. The illuminated version is also ideal for use in areas with limited light, such as hallways, stairways and emergency lighting. With its simple mechanics and robust construction, the PB400EEQR1BLK is an ideal solution for a number of different applications.
