This Siemens 52PX8A1J pushbutton unit has a black anodized pushbutton actuator with a black plastic cap and an assembled contact block, and is suitable for use in corrosive or oily environments. The flat-surface pushbutton actuates a normally closed (NC) contact for momentary on/off operation. The contact block is rated at up to 600V and up to 7,200W power input. The pushbutton unit has a 30 mm diameter shaft and is intended to mount in a Siemens enclosure (not included). This pushbutton unit is Underwriters Laboratories (UL) Listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for use in an application such as controlling an electrical circuit in a manufacturing process control system.

Pushbutton switches make or break electrical connections as part of a system that controls a process, such as a manufacturing line. Indicator lights with labels or color-coded caps are used to display the current state of a process, such as "completed." The pushbutton unit is composed of a pushbutton actuator for making or breaking electrical connections, a holder for securing the actuator to a control panel and for housing a light, and one or more contact blocks for connection to electrical wiring. Contacts within a contact block can be normally open (NO) or normally closed (NC), so that pressing the button starts or stops a process. Holders accommodate a range of control panel thicknesses and may include lamps to illuminate the button. Pushbutton actuator head types include mushroom, flat-surface, raised-surface, and key-operated, and may be illuminated, color-coded, and labeled. According to the requirements of an application, actuators may operate only as long as the button is held or they may lock into position when pushed and unlock when pulled or twisted. Pushbuttons and indicator lights are used in applications such as manufacturing process controls and as emergency shutoffs in industrial workplaces.
